Card 1 of 21
The argument of a trigonometric function is its [ ].
A
Negative arguments satisfy cos(−θ)=\cos(-\theta)=cos(−θ)= cosθ\cos\thetacosθ, sin(−θ)=\sin(-\theta)=sin(−θ)= −sinθ\boxed{-\sin\theta}−sinθ and tan(−θ)=\tan(-\theta)=tan(−θ)= −tanθ-\tan\theta−tanθ.
B
−33-\dfrac{\sqrt3}{3}−33.
C
12\dfrac1221.
D
The argument of a trigonometric function is its input.
