First, I'll talk about the limits. I understand most of it in class, until I see the homework problems and complete flip out.

1. Find the limit of:

a. Lim theta -> pie of theta sec theta

b. lim x->0 of sin5x/sin 4x

Knowing that lim as theta approaches 0 for sintheta/theta = 1 Find the limit of:

Lim h->0 sin(sinh)/sinh

Lim x-> 0, 6x^2(cotx)(csc 2x)

Find the average rate of change between -1 and 4;f(x) = -4x^2 - 6x +2

Thanks in Advance for the help.

P.S. how do you type mathematical signs on the keyboard? I've seen threads with them and was wondering how its done...
