1. you cannot draw it here. However, you can see them here:

http://www.wolframalpha.com/input/?i=plot+y%3Dtan%28x%29%2C+y%3D2cos%28x%29+for+x+%3D+-pi..pi

x is in radians, but the graphs look the same for degrees:

http://www.wolframalpha.com/input/?i=plot+y%3Dtan%28x*pi%2F180%29%2C+y%3D2cos%28x*pi%2F180%29+for+x+%3D+-180+..+180
