I tried this:
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.
Questions, comments, concerns and criticisms always welcome, John
