In product rule d/dx(uv) is equal to what?

A. u dv / dx + v du / dx

Step 1: Identify the concept: this is differentiation product rule. Step 2: Derivative of product of two functions is u dv/dx plus v du/dx. Step 3: Remember first into derivative of second plus second into derivative of first.

Step 1: concept पहचानें: यह differentiation product rule है। Step 2: दो functions के product का derivative u dv/dx plus v du/dx होता है। Step 3: First into derivative second plus second into derivative first याद रखें।
