According to the general form of a tangent, the Period should be |pi/b|, which is pi/(3/2) in this problem. But when I type it into my calculator(TI-83 Plus), it gives me 2.094395102. Now how am I supposed to graph that? Also, this calculator won't let me convert from decimal to fraction for some reason, so I don't know what to do. :/

If anybody can help me with this, I will love them forever. Lol.
