What trig function to use when a triangle with a missing side opposite of θ
Cosine θ = Adjacent / Hypotenuse

What trig function to use when a triangle with a missing side adjacent of θ
Sine θ = Adjacent / Hypotenuse

What trig function to use when a triangle with a missing side Hypotenuse of θ
Tangent θ = Opposite / Adjacent

to find θ knowing Opposite and Hypotenuse
Sin_{1}(Opposite/Hypotenuse) = θ

to find θ knowing Adjacent and Hypotenuse
Cos_{1}(Adjacent/Hypotenuse) = θ

to find θ knowing Opposite and Adjacent
Tan_{1}(Opposite/Adjacent) = θ
