Solve the following for cos²θ:
sin²θ + cos²θ = 1
cos²θ = 1 - sin²θ
cosθ = 1 + sin²θ
cosθ = 1 - sinθ
cos²θ = Adj/hyp

Solve the following for tan²θ:
1 + tan²θ = sec²θ
tan²θ = sec²θ + 1
tan²θ = sec²θ - 1
tanθ = secθ - 1
tan²θ = opp/adj

Rewrite tan(x) in terms of sin(x) and cos(x).
tan(x) = cos(x)/sin(x)
tan(x) = 1/cot(x)
tan(x) = sin(x)/cos(x)
tan(x) = opp/adj
