Suppose f(x)=2x^2-x^3 and g(x)= sin(pix/2).

a) What is the exact value of the integration from 0 to 2[f(x)-g(x). Find numerical approximation of this value. What does the value of this integral tell you about the areas of the regions beteen the two graph

I am uncertain of your questions about the three things you are asked to do.

The first is easy

The second you have to decide on the numerical model, I would use .1 divisions of x.

On the third, compare the value of the integral of 2(f(x)-g(x)) to the value of INT sin(PIx/2). That will be revealing.

Repost if you have a specific question.
