    Double Angle Equations!

    I need help with the steps leading from one function to the other? ... These are double angle identity conversions.

    • Cos --> cotangent
    • Cos --> sin2θ
    • Secent --> tangent
    • Cotangent --> secent
    • Cos2θ --> sin
    • Sin2θ --> cos

    Re: Double Angle Equations!

    I'm sorry, but I really don't know what you're trying to accomplish.

    what do you mean by cos -> cot ?

    with this, all I can tell you is

    \cos{x} \cdot \csc{x} = \cot{x}

    what does that have to do w/ double angle identities?

    Re: Double Angle Equations!

    There's double angle identity problems that require you to convert one function into another;

    like sin ---> csc; sin=2, so csc=1/2 because sin is the inverse of csc

    These are just more complicated conversion problems...
