Did you read the RULES? If so where is your own effort?

I know this has something to do with it, but I'm not sure where to go from here.

khbeast21,

Do you know what is trapezoidal rule?

If not do a Google search - may start here: https://en.wikipedia.org/wiki/Trapezoidal_rule

When -1≤ x ≤ 1 and n = 50, what would be your step size?
