WebbUsing one of the trigonometric identities, we have sin 2 x + cos 2 x = 1. Subtracting cos 2 x from both sides, we get sin 2 x = 1 - cos 2 x. Thus, one of the sin squared x formulas is, sin2 x = 1− cos2x sin 2 x = 1 − cos 2 x. Using one of the double angle formulas of cosine function, we have cos 2x = 1 - 2 sin 2 x. Webb$\begingroup$ Seems like you simplified $\sin^4 x - \cos^4 x$, not $\sin^4 x + \cos^4 x$. $\endgroup$ – lisyarus.

WebbSHORT ANSWER: Yes, you can use cases, but you should use three cases. The first case is sinx = 0, the second is cosx = 0 (since that is also a denominator in your equation), and the third is ... You're essentially there: y = x+cos(x) = 2π +2πk +cos(2π +2πk) = 2π + 2πk. There are infinitely many y -values, one for each k ∈ Z.
