Webcos − 1(cosx) = {x − kπ if k is even, (k + 1)π − x if k is odd. Proof. First, note that x − kπ and (k + 1)π − x are both in [0, π]. Moreover, if y ∈ [0, π], then cos − 1(cosy) 1 = y. Now, suppose k is even. Then cos(x − kπ) 2 = cosx and so: cos − 1(cosx) = cos − 1[cos(x − kπ)] 1 = x − kπ. Next, suppose k is odd.
