Firstly, it's not good to ask us to "do" it for you. We want to help you do it for yourself. There is a lot of material covered here. Are you familiar with definite integration? If so, you are supposed to calculate the real value of the integral so you can compare it against two other methods of approximation. The formulas for Trap. and Simp. rule should be in your textbook. I can walk you through it when I know how much you already know.
