For this problem, we know that the point negative 5, comma, 3 is on the terminal side of theta.
00:06
And we need to find cosine, sicken, and cotangent of theta.
00:10
So the first thing we need to do is draw a right triangle.
00:14
And then we know that the height of the triangle is the y value of the point, which is 3.
00:19
And the base of the triangle is the x value of the point, negative 5.
00:25
Then i'm going to find the hypotenuse, which i'm going to call c by applying the pythagallon theorem.
00:33
And so i have c squared equals 3 squared plus negative 5 square.
00:39
And then here, the right side simplifies to 34.
00:43
And if i squared root both sides, i get the c equals the square root of 34...
