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.
