What is the slope of the tangent to y = x^2 at x = 12?
वक्र y = x^2 पर x = 12 पर tangent की slope क्या होगी?
Show answer and explanation
Correct Answer
B. 24
ExplanationStep 1: The slope of a tangent is found using the derivative. Step 2: dy/dx = 2x, so at x=12, slope = 2×12 = 24. Step 3: When slope is asked, find the derivative first.
Step 1: Tangent की slope derivative से मिलती है। Step 2: dy/dx = 2x, इसलिए x=12 पर slope = 2×12 = 24। Step 3: Slope पूछे तो पहले derivative निकालें।
