Question

Let $cos^{-1}\frac{y}{b}$=$log_e (\frac{x}{n})^n$, then Ay2+By1+Cy=0 is possible : (where y2=$\frac{d^2y}{dx^2}$, y1=$\frac{dy}{dx}$)

• A. A=2, B=x2, C=n
• B. A=x2, B=x, C=n2
• C. A=x, B=2x, C=3n+1
• D. A=x2, B=3x, C=2n

Answer 1

Answer: (B)

A=x2, B=x, C=n2

Answer 2

The correct option is (B): A=x2, B=x, C=n2
