OK Now I understand. Thank You.

It is certainly helpful to keep it in the form e(1/2)x2 and now I see that the max value of the fourth derivative is 43e2. I am not sure why the first factor can be ignored, but for y = x4 + 6x2 + 3 I find a max value of 43 @ x=2. So, which is it 43 or 43e2(317.729)?

Homework Statement I am trying to write a program to calculate an integral using Simpson's Rule. My program also needs to calculate the error. In the formula for error I need The max value of the fourth derivative. The function is 2.718281828^{\frac{x^{2}}{2}} and the interval is from 0 to 2...

Still, I would appreciate feedback if anyone understands what they expect me to answer.
