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.
This should work. I used algebraic entry but textbook should work. Remember to purge(x) otherwise the assume(x....) remains.

I didn't know that was there, but it works perfectly.

Couldn't you also use the pipe key, though? The N-Spire does something like that.
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

Also check math template key. Easier.
