If y = x Sin x, find dy/dx when x = π/2
A.
−π/2
B.
-1
C.
1
D.
π/2
Correct Answer: 1
Explanation
y = xsinx dy/dx = 1 sin x + x cos x = sin x + x cos x At x = π/2 = sin π/2 + π/2 cos π/2 = 1 + π/2 × 0 = 1
y = xsinx dy/dx = 1 sin x + x cos x = sin x + x cos x At x = π/2 = sin π/2 + π/2 cos π/2 = 1 + π/2 × 0 = 1THIS WEEK's
