Trapezoidal Rule

[legacyofpiracy]

This was actually a three part question, but I was just getting stuck on the first part.

Given the following integral and value of n, approximate the following integral using the methods indicated (round your answers to six decimal places): 

 1
S  e^(-3x^2) dx,    n=4
 0

Trapezoidal Rule: ?

I think firstly I am just confused as to what I use the n=4 for :? Any suggestions?

n=4 is how many trapeziods you should use to estimate the area.

By the way, a bit off topic but I was just curious as to how I can post math symbols on here. For example integral signs, theta, squared, etc. Thanks.
