It is the same as to ask

        at what condition 2 is 3 ?

-------------

Comment from student :   Sorry I think I did not put question in right way. Question is following:

        At what point graph of inverse of Cosine of x and Inverse of Sine of x are same? [Hint: Sin(pi/4) = Cos(pi/4)

My response :   Your comment is perfectly right / correct.

But now, having the HINT, you just know the answer, as I see from your comment,
so, the only thing that remains for me, is to be glad seeing your progress (!)
