1.7.9 Solve simple trigonometric equations

Card 1 of 20

Why can an inverse trigonometric function alone miss solutions?

A

Sine and cosine only take values in [−1,1][-1,1][−1,1].

B

θ≈116.6∘, 296.6∘, 476.6∘\theta\approx116.6^\circ,\ 296.6^\circ,\ 476.6^\circθ≈116.6∘, 296.6∘, 476.6∘.

C

Trig functions are periodic, so several angles can give the same value.

D

θ≈1.911, 4.373\theta\approx1.911,\ 4.373θ≈1.911, 4.373.
