Consider the angle shown below 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). The terminal point is how many radius lenghts to the right of the circle's center?
h=

Then, cos−1(h)=

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

Therefore, θ=
