After I entered the integral, I open the Mathematics tab and clicked Compute | Calculate:

And the Mathematics Addin for OneNote and Word solved the integral. This is great! I'm having a blast (and I realize I'm gushing, but as a math guy, this is simply fun).

And I have to say I'm more impressed with solving the integral than creating the graphs, but both are excellent.  The top graph is a zoomed in and rotated version of the bottom.
