How do I answer questions like find all general solutions to :cos(x) = sin(x)?
I know I need to get 2 different equations like x = 2npi +/- ... for cos and x = npi + (-1)^n ... but how do I get it so that cos(x) = ... and sin(x) = ... so I can apply the formula to the equation
yea but that's not what I was meaning, I was meaning if there's an equation with sin(4x) = cos(5x) (as posted in my new thread) or something of that nature then how do i solve it not for the equation in the post above, was just meaning that sort of equation in general, sorry if I was unclear.
