Question
The terminal side of angle θ lies on the line y=-mx for m>0 and x>0.calculate the values of the trigonometric function
Answers
Reiny
slope of y = -mx is -m, but m is a positive number, so the slope is negative
the slope is also equal to tan Ø
the tangent is negative in quadrants II and IV, but x > 0 in IV
so 270° < Ø < 360°
