Hello, just going through some Riemann sum problems before I hit integrals and I am like 99% sure that this answer from my text is wrong but I want to make sure. It's not really an important question so if you have better things to do, help the next guy :) But checking this over would be appreciated!

I am trying to find an approximation of the integral using a Riemann sum.
Here is the question.

Why are they using 32 as the denominators for their endpoints? I have the same numerators but my denominator is 12 since [tex]\Delta x=\frac{\pi}{6}[/tex]. And for my first midpoint I would use half that.. [tex]\frac{\pi}{12}[/tex], and then add delta x again n times, right?
