Okay, so this point will be in the third quadrant.
00:08
So we'll have the point will be somewhere here.
00:14
Our terminal side will pass through this point, and our angle starts here, stops at the terminal side, theta.
00:26
And we can draw a perpendicular line from the x -axis to the point here.
00:36
Now we have a right triangle.
00:40
The vertical side here is negative 3.
00:43
That's y.
00:44
And x is going to be negative 4.
00:46
It's horizontal side.
00:47
And i don't know what r is.
00:49
So that's what we're going to find.
00:52
So first, we'll find r...
