Answers:

  • a) True
  • b) False
  • c) True

====================================================

Explanations:

  • a) y = sin(theta) describes the height of the point (x,y). Because m = sin(theta), this means m is the height.
  • b) Cosine is not positive in quadrants II and III, where x < 0. This is because x = cos(theta).
  • c) Adding pi radians to the angle theta will rotate it 180 degrees to have it land in the fourth quadrant (southeast quadrant).
