If y = (x+1)/(x-1) then what is dy/dx?
यदि y = (x+1)/(x-1) है तो dy/dx क्या होगा?
Show answer and explanation
Correct Answer
B. -2/(x-1)² / -2/(x-1)²
ExplanationStep 1: Use quotient rule. Step 2: derivative = [(x-1) - (x+1)]/(x-1)² = -2/(x-1)². Step 3: In quotient rule do not reverse the order of terms.
Step 1: quotient rule लगाएं। Step 2: derivative = [(x-1) - (x+1)]/(x-1)² = -2/(x-1)²। Step 3: quotient में numerator और denominator का order न बदलें।
