Integrate question

[webmasterpdx]

I'm not saying the CAS and wxMaxima results are the same....they are equivalent! i.e. Let CAS result = f, wxMaxima = w. Then f = w + constant. It doesn't matter if f(x) != w(x) for a specific x, because it's an indefinite integral. That would only apply if you had a definite integral over the same interval.

I'm only saying that if g = trigsin(f), then g(x) = f(x) (nothing to do with wxMaxima).
This is where the constant comes from. When you expand f(x) into sins, you'll get some sin(pi/2) terms and this is where the 1/48 comes from.....i.e. It is correct.

Also, as long as f(x) = w(x) + constant, then both f(x) and w(x) are solutions to the INDEFINITE integral, and are thus correct answers.
