Question

The area bounded by curves y = cos x and y = sin x and ordinates x = 0 and x = π/4 is

(A) √2

(B) √2 + 1

(C) √2 - 1

(D) √2(√2 - 1)

Answer 1

Answer is (C) √2 - 1

Given equations of curves y = cosx and y = sinx and ordinates x = 0 to x =π/4.

We know that area bounded by the curves is
