Given sin θ =
1. Draw a non-unit circle placing in the triangle in the appropriate quadrant.
2. Label/find the sides of the triangle. Don't forget the check the sign.
3. Now the other 5 trig functions can be easily found from these sides.
x2 + 22 = 32
x2 = 5
In this case we are in the 2nd
quadrant so it must be negative.
