If y=(x+1)^2 then what is dy/dx?
यदि y=(x+1)^2 है तो dy/dx क्या होगा?
Show answer and explanation
Correct Answer
A. 2(x+1)
ExplanationStep 1: Identify the concept: this is a simple use of chain rule. Step 2: Derivative of (x+1)^2 is 2(x+1) and derivative of inside x+1 is 1. Step 3: Remember outer derivative then inner derivative.
Step 1: concept पहचानें: यह chain rule का simple use है। Step 2: (x+1)^2 का derivative 2(x+1) और अंदर x+1 का derivative 1 है। Step 3: Outer derivative फिर inner derivative याद रखें।
