Tutorial for the Equation Editor in Microsoft Office by Dr. Mojtaba Mirsalim

1. Tutorial for the Equation Editor in Microsoft Office by Dr. Mojtaba Mirsalim Though it is expensive, we chose Microsoft Office because many of our students own the package already and because it will be a valuable addition to your software collection long after the course is over, and because much of our mathematical communication during the semester will happen in power points and then in MATLAB.

2. If you already have Microsoft Office on your computer, lets hope that Equation Editor has already been installed. Equations can be inserted into Word, PowerPoint, or any application that supports OLE (Object Linking and Embedding). • Open a document in Microsoft Word • Click on the menu item INSERT • Towards the bottom of the list choose OBJECT • Scroll through the list of objects looking for EQUATION EDITOR or for MICROSOFT EQUATION • If you cannot find it, you will have to reinstallMicrosoft Office. You can install Equation Editor through either custom installation or complete installation. A complete description about using the equation editor is available under Help in the equation editor window.

3. To insert an equation, choose Insert, Object, Microsoft Equation 3.0, and click OK . One of 2 things will happen: • A highlighted area will appear, along with equation editing palettes. This is known as in-place editing. It can be very difficult to see what is being entered. OR • A separate window will open, with the palettes on top. This is much easier for entering equations. This looks like the following.

4. To exit and return to your Word document you may choose File/Exit and Return to (Document Name); to update the Word document but remain in the equation editor you may choose File/Update. • In-place editing is the default, but it is possible to have a separate window for EQUATION EDITING (remind me to talk about it later, next week).

5. Once you have the Equation Editor installed, you can have an icon placed in your toolbar for easy access. • Click View/Toolbars • Select Customize/Commands • Select Categories/Insert • Under Commands, scroll down to Equation Editor • Hold and drag the Equation Editor icon up to any existing toolbar/gray area that will accept it. • You can do the same thing in Power Point. • You are now ready to learn how to use your Equation Editor. Your icon should look like this

6. When you double-click on the icon for the Equation Editor, the window below should open up. Each button on the menu bar gives you a sneak preview to the many options that are available to you when you click that button.

7. The buttons that you will use most frequently are described below. Grouping symbols with absolute value bars Fraction and root icons Greek letters including pi and theta Exponents and subscripts

8. So, lets see if you can create the following expression: Click on the Equation icon. You can create exponents from the Equation menu bar but the keyboard shortcut for exponents is Ctrl & H. You can remember this because H stands for “high” and exponents are a little high. Type 3x followed by Ctrl & H. An icon should appear in the exponent slot. Type 4 and then hit Tab to get out of the exponent. Continue in this fashion until you are done with the expression. When you are done click on the document outside of the Equation Editor work area and the expression that you created will be inserted into your Word document. The size can be adjusted by clicking on the equation once and dragging the corners out to the preferred size.

9. Here are some other short cuts that will make your life easier: • Ctrl & F for fractions, • Ctrl & R for square roots but for other roots use the tool bar, • Ctrl & L for subscripts, • Ctrl &( or Ctrl &) for parentheses that grow with your expression. • Use the Tab key to escape from each of the above modes. • Ctrl & space bar will create small spaces if you need them. • Ctrl & I for Definite Integral, • Ctrl & G for inserting Greek letters, followed by a letter key • Ctrl & Shift & E for adding plain text • Ctrl & Shift & = for going back to math after adding text

10. Now see if you can create the following expression before you move on to the next frame. If you have not already done so, create a Word document in which you can practice while you are working with this tutorial.

11. Now lets see how you do with the Quadratic Formula: You can find the plus-or-minus symbol in one of the palettes in the menu bar.

12. Type x = • Press Ctrl & F for the fraction • Type –b • Click on the palette that contains the plus-or-minus symbol in the menu bar • Click on the plus-or-minus icon • Press Ctrl & R to create the root • Type b and press Ctrl & H • Type 2 and press Tab • Type –4ac and press Tab to escape the root • Press Tab to enter the denominator and type 2a

13. Now, try to solve the following equation by multiplying both sides of the fraction by the 12x(x + 1).

14. With a construction this large, you should probably copy it before you click out. You don’t want to lose it. Good luck.

15. Now, you are ready for the following assignments: The following time sequence r(kT) may be determined from R(z) by use of the inversion formula, which is a contour integration along the path , where  is a circle of radius centered at the origin in the z-plane, and c is of such a value that all the poles of R(z) are inside the circle.

16. The Discrete Cosine Transform (DCT) The orthogonal sequences are defined on [0, N-1] by One can verify that where

18. Equation Editor Tips & Tricks Here are some tips and tricks for getting the most out of Equation Editor. Except where indicated, these tips should work for all versions of Equation Editor . Editing equations in a separate window rather than "in-place" Some Equation Editor users prefer to have a separate window open each time they create or edit an equation, rather than the default "in-place" editing. There are several possible reasons to prefer "open mode" editing over in-place: The viewing scale of the equation windows can be controlled independently of the viewing scale of the word processing or presentation window. Whereas you might want to edit your document at a scale of 100% or 125%, equations are sometimes hard to read and edit at such scales. We recommend using 200% scale in your equation windows. The menus and toolbars of your word processor don't jump around when switching back-and-forth between equation editing and document editing. By opening Equation Editor in a separate window, you can keep it open and use it as an "equation scratchpad".

19. The easiest way to do this is to run Equation Editor as a separate application. To make this convenient, you need to find out where Equation Editor is located on your computer's hard disk and make a shortcut to it. Here's how to do this: Windows: Use the Find Files or Folders command on the Start menu to find a file named EQNEDT32.EXE (or EQNEDIT.EXE on some systems). Once you have found the file, make a shortcut to it on your desktop or in the Start menu. Consult your Windows documentation if you don't know how to do this. The default location is C:\Program Files\Common Files\Microsoft Shared\Equation.

20. Whenever you start working with equations, first run Equation Editor by using the shortcut you created. Equation Editor will open a new empty equation window that is not associated with any equation in any document. You can use this window as a scratchpad, placing any equation or expression in it that you want and using cut-and-paste or copy-and-paste to transfer expressions into the documents you create. Once you have started Equation Editor this way, you still insert new equations as you usually do. Keep an Equation Editor window open to make equations open faster (look at the next slide)

21. Formatting equations with numbers to the right Display equations are equations that are placed in their own paragraph, as opposed to "inline" or "text" equations which are placed in the same line as normal text. Although there are many ways to format these, the most common is to center the equation between the margins and insert an equation number to the right of the equation, flush against the right margin. This is easy to do in most, if not all, word processors. The basic idea is to place a centering tab-stop centered between the left and right margins and a right-justifying tab-stop placed exactly on the right margin. For each equation, create a single paragraph containing the following items from left-to-right: a tab, the equation, another tab, the equation number. Here's what this looks like in Microsoft Word (the tab-stops have been circled in red):

22. Template "wrapping" and replacement Have you ever typed an equation, then realized it would be easier to read if this big expression were enclosed in parentheses? Or, perhaps your equation uses a summation template without limits, then you decide it really must have limits after all. Both of these situations can be handled quickly without having to re-type the equation or do a big cut-and-paste job. What you need is template wrapping in the first case and template replacement in the second. Template wrapping Let's start with a common statistical formula:

23. But now we notice a problem! The 1/n should apply to the entire right side of the equation. Let's indicate this by putting parentheses around it and, because we want the parentheses to be big enough to unambiguously enclose the expression, we'll use a parenthesis template. Wrapping is easy; just select the part of the equation to be wrapped: Now insert the wrapping template in the normal way. An inserted template will wrap itself around anything that is selected. So now our expression looks like this:

24. Template replacement Now we see another problem: the summation is supposed to have limits. To fix this we'll use template replacement. First, select the template and its contents: Next, hold down the Alt key (use the Option key on the Macintosh). With the Alt key depressed, press and hold the left mouse button until the mouse pointer is over the template you want. When the pointer is over that template, release the mouse button, then release the Alt key. In this case, we choose the summation with upper and lower limits. All that is left is to type in the limits and we are done:

25. Putting a box around an equation Often it's helpful to include an equation enclosed inside a box, either for emphasis or to set it apart from the surrounding data. This is a great way to highlight the answer to an example problem, such as: To do this, first create a 1-by-1 matrix. In the matrix dialog box, click in the preview pane outside the matrix on all four sides. This will insert solid lines around the matrix. If you want the lines to be dashed, click twice. If you want them dotted, click three times. Click once more to remove a line.

26. Use matrices to create simple blank grids Equation Editor's matrix templates can be used for all kinds of things. For example, here is a blank grid that could be useful in a test or a quiz calling for students to graph a function: To create such a grid, you just insert a matrix with the appropriate number of rows and columns and add partition lines between the elements. These lines can be solid (click once between rows or columns), dotted (click twice), or dashed (click 3 times).

27. Animated equations in PowerPoint you can use Equation Editor with PowerPoint to create presentations containing equations. Here we'll show you an additional technique. Insert your equation into PowerPoint as described above. Right-click on the equation, and from the menu select Grouping/Ungroup. A dialog will appear with a warning about the action you’re about to do. Click Yes. Your equation will then appear as individual characters and templates, which you can animate individually using SlideShow/CustomAnimation.

28. To change the color of an equation inserted into PowerPoint Although most equations you create will be black text on a white background, very often slide presentations are created with colored text on a dark or black background. Although Equation Editor cannot create colored equations, PowerPoint gives you the ability to change the black and white of your equations to whatever background color and foreground color you want. Here's how to color an equation:

29. 1) Insert the equation into the slide the usual way using Insert Object. 2) Right-click the equation object to bring up a menu of commands. 3) Click on "Format Object", the last item on the menu. This will bring up a dialog. 4) Click the tab titled "Picture". Under the Picture tab, click "Recolor". When the "Recolor Picture" dialog appears, you can change the color. There should be black and white rectangles in the "Original" section. Here you can change both the white background and the black text color, or either of them individually. Click the dropdown box next to the black color in the "New" column; you can select any color shown there. You can preview your selection to see if the color is what you had in mind. If it looks fine, click OK on both dialogs.
