Right, giving a solution that doesn't involve L'Hopital's Theorem (which he likely doesn't know as this is a limit problem that is commonly given near the beginning of a Calc 1 class) makes me slow.

Not for 0 <= x < pi/2. Example: sin(pi/4) = sqrt(2)/2 = 0.707..., pi/4 = 0.785..., tan(pi/4) = 1. In the other interval, -pi/2 < x <= 0, then you are correct as I said in my post. In short, you fail.

We were taught L'Hopital's at the beginning of calc limits too.

Calculus classes almost always teach limits before the derivative, since that is the way that makes sense. If your teacher did it differently it was a stupid choice on his or her part as it is not possible to do even a halfway decent job of defining the derivative without the notion of a limit.
