If y = x² sin x then what is dy/dx?
यदि y = x² sin x है तो dy/dx क्या होगा?
Show answer and explanation
Correct Answer
A. 2x sin x + x² cos x / 2x sin x + x² cos x
ExplanationStep 1: Use product rule because it is a product of two functions. Step 2: The derivative is 2x sin x + x² cos x. Step 3: The derivative of uv is u'v + uv'.
Step 1: product rule लगाएं क्योंकि दो functions का product है। Step 2: derivative = 2x sin x + x² cos x। Step 3: uv का derivative u'v + uv' होता है।
