1) Determine the values of the trigonometric functions of the angle (smallest positive angle) if P is a point on the terminal side and is the coordinates of P are P( -1, -3).

2)Find the diameter of a pulley which is driven at 360 r/min by a belt moving at 40 ft/s.

3) State the quadrant in which the angle terminates and the signs of the sine, cosine, and tangent of the angle of 212 degrees.

The teacher never went over this and i'm at a complete loss.
