# Math Help - Double Angle Equations!

1. ## 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

2. ## 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?

3. ## 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...
