# Inverse differentiation?

- Enter the function y(t)=t^3-2*t+1 for -2<=t<2 and display the function only.

- Create a screenshot of your display.

- Now display the derivative and save the derivative values to a file.

- Open the derivative values file, reading in the derivative as a new function.

- Calculate the integral of this function, using an initial value of t=0, and display the integral only

- Create a second screenshot

- How are the two graphs in the screenshots different?

- Why are they different?

- Can you change the setup values and the initial value for t and replot the graphs so as to be as similar as possible?
