Slope Fields Slope fields are a way to visualize answers when you… • Start with the derivative, and • Need the original equation.
Slope Field Questions • You have a derivative. • You don’t know what the original function is. • You don’t know how to find it. • But you can tell what it looks like by creating a slope field. Create a slope field for the following differential equation.
Slope Field Questions Step one: • Pick a point. • Consider its coordinates. • Plug these x and y values into the derivative. Create a slope field for the following differential equation. (0, 1) x = 0, y = 1 dy/dx = x + y = 0 + 1 = 1 So, at (0, 1), dy/dx = 1
Slope Field Questions Step two: • At this point, imagine sketching a line with a slope equal to dy/dx. x = 0, y = 1 dy/dx = x + y = 0 + 1 = 1 So, at (0, 1), dy/dx = 1 Create a slope field for the following differential equation. m = 1 (0, 1)
Slope Field Questions Step three: • Just draw a little piece of this line, centered at the point. x = 0, y = 1 dy/dx = x + y = 0 + 1 = 1 So, at (0, 1), dy/dx = 1 Create a slope field for the following differential equation.
Slope Field Questions Now…Repeat: • With many more points! Create a slope field for the following differential equation. (-1, 1) x = -1, y = 1 dy/dx = x + y = ______ = ____ So, at (-1, 1), dy/dx = ____
Slope Field Questions A solution • Might look like this. Create a slope field for the following differential equation.
