Our job is going to be to simplify, again, cosine squared theta, secant theta, co -secretta, this time.
00:09
So that's the question.
00:11
And what i'm going to suggest you do in terms of a strategy, whenever you're approaching these questions, is if you have a string of multiplication.
00:18
So you've got this thing multiplied by this thing, which is then multiplied by this thing, this function.
00:24
The strategy to simplify is to get everything in terms of sine and cosine.
00:29
So cosine squared theta already is in terms of sine.
00:32
And cosine.
00:34
Then we're going to write secant theta is one over sine theta.
00:38
Sorry, one over cosine theta.
00:40
I'm jumping ahead here...
