Okay, so i'm given some information about an angle, and then i want to find cotangent of theta.
00:11
Okay, so let's see.
00:12
Co -secent of theta is negative 3 over 2.
00:16
Since co -secent is the reciprocal of sine, i know that sign is then negative 2 thirds.
00:22
You don't have to do that.
00:23
I find it easier to work with the big 3, sine, cosine, tangent, and then flip.
00:29
So, sine is negative, right? because this is a negative two -thirds.
00:33
That means i can't have this angle in quadrants one or two, where sign is positive.
00:40
That's what this next statement is for.
00:42
Now i have to determine is it three or four...
