Question

The graph of which function passes through the point ( 0,pi/2 )

Answer 1

y = cos ^- 1 (x)

Step-by-step explanation

Answer 2

y = cos ^- 1 (x)

Explanation:

The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
