Did you try to plot the graph? I did and got this result.

anonymous · Answer

try using an online calculator like this one. https://www.desmos.com/calculator# enter xtanx as your equation. there are x-axis settings below that you can convert your x-axis to term of pi. the graph is very interesting, as you'll see.

See the attached file for the full plot of the function. The function has an infinite value when x = pi/2 and x = -pi/2.
