What is the value of ∫ sec² x dx?
∫ sec² x dx का मान क्या है?
Show answer and explanation
Correct Answer
A. tan x + C
ExplanationStep 1: Identify the concept: this is standard trigonometric integral. Step 2: Derivative of tan x is sec² x so the integral is tan x + C. Step 3: Remember sec square integrates to tan.
Step 1: concept पहचानें: यह standard trigonometric integral है। Step 2: tan x का derivative sec² x है इसलिए integral tan x + C होगा। Step 3: sec square integrates to tan याद रखें।
