    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
