JEE Mains · Maths · STD 12 - 5. continuity and differentiation

જો \(\log _e y=3 \sin ^{-1} x\) હોય, તો \( x=\frac{1}{2}\) પર \(\left(1-x^2\right) y^{\prime \prime}-x y^{\prime}\) બરાબર ........... છે.

  1. A  \(9 e^{\pi / 6}\)
  2. B \(3 e^{\pi / 6}\)
  3. C  \(3 e^{\pi / 2}\)
  4. D  \(9 e^{\pi / 2}\)
Verified Solution

Answer & Solution

Correct Answer

(D)  \(9 e^{\pi / 2}\)

Step-by-step Solution

Detailed explanation

\( \ln (y)=3 \sin ^{-1} x \) \( \frac{1}{y} \cdot y^{\prime}=3\left(\frac{1}{\sqrt{1-x^2}}\right) \) \( \Rightarrow y^{\prime}=\frac{3 y}{\sqrt{1-x^2}} \text { at } x=\frac{1}{2} \)…
