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

- Cos --> cotangent
- Cos --> sin2
θ- Secent --> tangent
- Cotangent --> secent
- Cos2
θ--> sin- Sin2
θ--> cos

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

what does that have to do w/ double angle identities? - Nov 28th 2012, 02:16 PMwhittwhittRe: 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... - Nov 28th 2012, 02:36 PMskeeterRe: Double Angle Equations!
post one of the problems including all given information and directions ...
