00:01
So i see you have numbers 11 and 14 circled, so that's going to be the one i'll do.
00:05
So let's start with number 11.
00:07
That gives you the points 4, 3, 4, 3.
00:12
We want to find all the trigonometric ratios.
00:14
So i'm going to create my triangle.
00:16
And i see that we have an x value of 4, a y value of 3.
00:20
This creates a pythagorean triple, so i know that we have a hypotenuse of 5.
00:25
So i'm going to look at my angle theta.
00:27
And we're going to go sine theta, tangent theta.
00:31
Oh, i meant to put cosine theta.
00:34
Tangent theta.
00:36
So sine theta would be opposite over hypotenuse.
00:39
That would be 3 over 5.
00:41
Cosine would be 4 over 5, adjacent over hypotenuse.
00:45
Tangent would be 3 fifths...
