# Inverse integration?

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

- Create a screenshot of the drawing.

- Now display the integral, calculated with an initial t value of -2 and save the integral values to a file.

- Open the file, reading in the integral as a new function. Calculate the derivative of this function, using the forward difference method, and create a screenshot of this derivative.

Now answer the following:

- In what way do the two graphs in the screen shots differ?

- Why are they different?

- Can you change the display setup to replot the graphs so as to be as similar as possible?
