What is ∫ cos(8x) dx?
∫ cos(8x) dx क्या होगा?
Show answer and explanation
Correct Answer
C. sin(8x) / 8 + C
ExplanationStep 1: The integral of cosine is sine and we divide by the inside coefficient. Step 2: ∫cos(8x)dx = sin(8x)/8 + C. Step 3: The reverse of chain rule becomes division in integration.
Step 1: cos का integral sin होता है और अंदर के coefficient से divide करते हैं। Step 2: ∫cos(8x)dx = sin(8x)/8 + C। Step 3: Chain rule का reverse integration में division बनता है।
