Choice (b) is correct.
This question related to Chapter 13 maths Class 11th NCERT. From the Chapter 13: Statistics. Give answer according to your understanding.
Choice (b) is correct. Let y = (sin x + cos x)² = sin² x + cos² x + 2 sin x cos x = 1 + 2 sin x cos x dy/dx = d/dx (1 +2sin x cos x) = d/dx (1) + 2 d/dx (sin x cos x) ⇒ dy/dx = 0 + 2 ( sin x (d/dx) cos x + cos x(d/dx) sin x) = 2 {sin x (- sin x) + cos x (cos x)} ⇒dy/dx = 2(cos² x - sin² x) = 2 cos 2Read more
Choice (b) is correct.
Let y = (sin x + cos x)² = sin² x + cos² x + 2 sin x cos x = 1 + 2 sin x cos x
dy/dx = d/dx (1 +2sin x cos x) = d/dx (1) + 2 d/dx (sin x cos x)
⇒ dy/dx = 0 + 2 ( sin x (d/dx) cos x + cos x(d/dx) sin x) = 2 {sin x (- sin x) + cos x (cos x)}
⇒dy/dx = 2(cos² x – sin² x) = 2 cos 2x
