Solving Trig Equations for a Certain Domain
I'm not sure how to receive the answers in terms of pi to equations like in the attachment to a certain domain.
With no arguments, the answer (pi*n, ((4*pi*n)pi)/4) is displayed. But to restrict to an interval like 0 to 2*pi, I can only find this (see picture). Although the solutions are displayed, they are in numeric form. How can I display the exact answers (0, 3pi/4, pi, 7pi/4) on the calculator? I am using Rev 6031 on the emulator.

Yep you are right, the "where"  works too without having to purge(x) > thanks!
add solve(tan...)(x>0 AND x<2*pi)

I tried doing the same before, but I had improper syntax. Thanks for giving me the proper form.

How exactly can I find the pipe symbol ?
Thanks Edit: Found it, on Chars, the 124th.
