State the domain for which the inverse function is decreasing.

Don't really understand this question...

inverse function of y=cosx (which is y=cos^-1(x))
Answered by R_scott
if you look at the unit circle

cosine decreases continuously from zero to π
Answered by oobleck
take a look at the graph. it increases on [-1,1] but you need to restrict the domain of cos(x) to [-π,0] or [π,2π], etc.
