Note:
sin x + cos x = 0 at x = 3π/4
So the function cos x/(cos x + sin x) tends to infinity as x tends to 3π/4 and hence improper integral should be used.
sin x + cos x = 0 at x = 3π/4
So the function cos x/(cos x + sin x) tends to infinity as x tends to 3π/4 and hence improper integral should be used.
