Halp!

I need help on a calculus problem. Does anyone know the answer (or can point me in the right direction) on this: What is the limit as x approaches 0 for tangent squared over x

You all suck.  Whenever you're doing a limit problem where x is going to zero and you've got trig functions, you can always replace sin(x) or tan(x) with x and evaluate the limit.

Tan(x)^2/x -> x^2 /x = x which goes to 0.
