Oops, sorry, didn't clarify it good enough.
The 4 is the exponent, and the x is a regular old number....so like![[Image: gif.latex?cos%5E4x]](http://latex.codecogs.com/gif.latex?cos%5E4x)
.
I don't know the Wolfram Alpha. I'm also not quite sure you can pull the sin^x + cos^x = 1, as you can't pull out a ^2, can you?
Edit:![[Image: gif.latex?y=f(x)=arccos(cos%5E4x-sin%5E4x)]](http://latex.codecogs.com/gif.latex?y=f(x)=arccos(cos%5E4x-sin%5E4x))
