  9. Student Work Zach Richardson Math 253 Project Fall 2012 As n grows larger, more wedges protrude from the service of the sphere. The number of wedges appears to be equal to the value of n. The value of m seems to shift horizontal sections of the sphere alternately so that they appear “off center”. As m grows larger, there are more such shifted sections.

  10. Student Work Zach Richardson Math 253 Project Fall 2012 Rather than dividing the sphere vertically or horizontally, when both n and m vary the sphere becomes deformed by bumps which could be caused by the two types of wedges intersecting. The number of bumps appears to be dependent on the product of n and m so if you know their values you can predict how many bumps there will be. As b grows larger, the space between the bumps, the valleys, becomes more pronounced and seems to cut deeper into the sphere.

  11. Student Work Zach Richardson Math 253 Project Fall 2012 Assignment 5 As a grows larger, the valleys grow less noticeable and soon appear to disappear altogether. Also, as a increases so does the radius of the sphere. When a > 5b the valleys are either gone or extremely shallow. When 5b > a the valleys become more noticeable as the difference between the two increases. Result from doing this project: Students should realize the importance of spherical coordinates. Gain experience analyzing a family of functions. Appreciate the power of computer software programs such as mathematica .
