Mark the tick against the correct answer in the following:
Range of cos-1 x is
To Find: The range of
Here,the inverse function 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 range of
From the graph, it is clear that the range of is restricted to the interval
