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

Now answer the following:

1. How are the two graphs in the screenshots different?
   
2. Why are they different?
   
3. Can you change the setup values and the initial value for t and replot the graphs so as to be as similar as possible?
