A point P lies on the unit circle such that its x-coordinate is x=−23 and the corresponding angle θ is known to satisfy π<θ<2π.
a. (i) Find the y-coordinate of P.
b. (ii) List all angles in the interval (0,2π) that share the x-coordinate x=−23.
c. (iii) Identify the value of θ satisfying π<θ<2π and express it in both radian and degree measure.
