WebJan 2, 2024 · ThePythagoreanIdentity is still true when we use the trigonometric functions of an angle. That is, for any angle, cos(θ)2 + sin(θ)2 = 1. In addition, we still have the inverse trigonometric functions. In particular, θ = arcsin(x) = sin − 1(x) means sin(θ) = x and − π 2 ≤ θ ≤ π 2 or − 90 ∘ ≤ θ ≤ 90 ∘. rowayton ct historyWebLet r be the distance from ( x, y) to the origin.
