Question

Consider an angle with an initial ray pointing in the 3-o'clock direction that measures θ radians (where 0≤θ<2π). The circle's radius is 2 units long and the terminal point is (−1.15,−1.64).

1. The terminal point is how many radius lenghts to the right of the circle's center?

      h=

2. Then, cos−1(h)=

3. Does the number we get in part (b) give us the correct value of θ?

4. Therefore, θ=
