Remarks
(i)
We know from Chapter 1, that if y = f(x) is an invertible function, then  x = f –1 (y) Thus, the graph of sin–1 function can be obtained from the graph of original
function  by interchanging x and y axes, i e , if (a, b) is a point on the graph of
sine function, then (b, a) becomes the corresponding point on the graph of inverse
