First, is the coefficient of x^2 supposed to be 0?
Second, is n just the number of subintervals you're supposed to use? What's all this about the parity? Just break the integral into three parts and use the approximation .
Use the Midpoint Rule to approximate the integral with n=3
***The problem I'm having is, isn't there a rule that states that n has to be an even number? So how does this work?
First I am quite sure there is a typo in this post
Now, with the midpoint rule n does not have to be even.
The division points are .
The midpoints are .
The midpoint sum is .
