Mark the tick against the correct answer in the following:

Domain of cos-1 x is


To Find: The Domain of


Here,the inverse function of cos is given by y =


The graph of the function y = can be obtained from the graph of


Y = cos x by interchanging x and y axes.i.e, if (a,b) is a point on Y = cos x then (b,a) is the point on the function y =


Below is the Graph of the domain of



From the graph, it is clear that the domain of is [-1,1]
