1.5.1 Definitions for all arguments

The argument of a trigonometric function is its [     ].

A

Negative arguments satisfy cos⁡(−θ)=\cos(-\theta)=cos(−θ)= cos⁡θ\cos\thetacosθ, sin⁡(−θ)=\sin(-\theta)=sin(−θ)= −sin⁡θ\boxed{-\sin\theta}−sinθ​ and tan⁡(−θ)=\tan(-\theta)=tan(−θ)= −tan⁡θ-\tan\theta−tanθ.

B

−33-\dfrac{\sqrt3}{3}−33​​.

C

12\dfrac1221​.

D

The argument of a trigonometric function is its input.
