4-123.

Given sin *θ* = *θ* <* *. Find the values of the 5 other trigonometric functions. Homework Help ✎

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.

*x*^{2} + 2^{2} = 3^{2}

*x*^{2} = 5

In this case we are in the 2nd

quadrant so it must be negative.
