Is tanx periodic and if not, why not?
I just found in my book that tanx isn't periodic, and how do we make up a rule how to seek periodicity of functions. I.e. ln(sin(x)), e^sin(x)... etc

Find a constant a such that f(x+a) = f(x). So basically you can solve for a function a(x) here, and make sure its a constant function.

Plot the graph. Notice that if you erase the coordinate axes you can still see where the origin must lie.
