For your problem here, we're really focusing on the co -secant function.
00:05
The first question there wants to know, how is the co -secant function defined? now, it does reference to section 1 .6, so what i might say might be different than that section does reference.
00:15
But there's a couple of ways that you can look at the co -seacan function.
00:19
The first thing is, is it's the reciprocal of sign.
00:24
So this is why we have ourselves opportunities for asymptotes, because there are places where sign is equal to zero, and where sign is equal to zero, we'll have the asymptotes for the co -sicant.
00:35
In terms of a right triangle, so if you think about a right triangle here, and here's our angle and our right angle, typically the sign of this angle here is opposite over hypotenuse.
00:44
So this would be o, this would be adjacent, and this would be our hypotenuse.
00:49
So that would be opposite over hypotenuse.
00:52
So for co -sicant, being the reciprocal in terms of the right triangle here is going to be the h over a or hypotenuse over opposite...
