The area formed by triangular shaped region bounded by the curves y = sin x, y = cos x and x = 0 is
Answer & explanation
Correct answer: option 1
Area $=\left|\int\limits_0^{\pi / 4}(\sin x-\cos x) d x\right|=\sqrt{2}-1$
(∵ y = sin x and y = cos x meet when sin x = cos x ⇒ x = $\frac{\pi}{4}$)
Hence (1) is the correct answer.
