Find the signs of the six trigonometric functions for the given angle.
--10°
A)Positive: all
B)Positive: cosine and secant; negative: sine, tangent, cotangent, cosecant
C)Positive: tangent, cotangent; negative: sine, cosine, secant, cosecant
D)Positive: sine and cosecant; negative: cosine, tangent, cotangent, secant

Question

Quizplus · Accepted Answer

Angles measured in negative degrees indicate rotation in the clockwise direction from the positive x-axis. A -10° angle lies in the fourth quadrant, where cosine and secant (the reciprocal of cosine) are positive, while sine, tangent, cotangent, and cosecant are negative.
