@Markiyan Hirnyk This solution is sufficient. I can confirm that it, indeed, works. I don't know if it is appropriate to pose another problem that it is closely related to this one, but here goes:

If I change the problem to 2*sin(2*x+Pi/4), and the desired form is sqrt(2)*sin(2*x)+sqrt(2)*cos(2*x), expand(,trig) no longer works for me. How might this one be tackled? Clearly, one may just replace "x" with "2x," but is this the only way?

@Carl Love I knew it had to be something simple. Your explanation is very good!

@Carl Love Yes, I realized that after I posted the question.

@Markiyan Hirnyk This works too, thanks!

@Carl Love This is just what I need. Thanks!

@nm Hence my question. My point is, that answer is not correct. Why is Maple not giving the correct answer?

@spradlig Despite it's convenience, be wary of RealDomain. See http://www.mapleprimes.com/questions/131296-Discrepancy-With-Limit

@Carl Love 

Yes, you are correct. I simply copied and pasted the command from the original question and added explicit. I wouldn't have constructed the command in that manner. :-)

Yes, I was able to get the value of 26Pi by manually converting it to cylindrical coordinates. I was wondering if there is a way to prod Maple to do the conversion on its own.

It does help, thanks!

It does help, thanks!

i use the 'explicit' option in various solvers, but never solve(). Thanks for the very detailed response.
