How to evaluate this limit without using L'hopital's rule

Your teacher that you are referring to is your calculus teacher, not your algebra or trigonometry teacher. The perquisite for calculus is algebra and trigonometry.

You need to factor and/or use a popular trig identity. Give it a try.

I would express what you need to do a little differently; maybe I'm just seeing a different way to solve it.

Please show us what limits you have learned; you will need to know, probably, two basic trigonometric limits. If you haven't been taught anything at all about limits, then there is a problem. If you have learned the limits I have in mind, then you need to do a little algebra.

The more you show us of what you know, and what you have tried, the better we can help.

Almost every time you have a trig limit and direct substitution gives an indetermined form you need to get sinx/x or x/sinx (possible the angle may not be x, but in this example it is)
