sin2x + cos2x = 1
but would sin23x + cos23x = 1?
Homework Equations
none.
The Attempt at a Solution
[/B]
I'm pretty sure sin23x + cos23x can't equal 1 otherwise the identity would probably be written as sin2cx + cos2cx = 1 and I've never seen it written like this.
I was doing a homework problem and i ended up in a situation where, if i could use sin2cx + cos2cx = 1, i'd get my answer. But I am doing it differently than the book, so my way might be wrong
