JEE Mains · Maths · STD 12 - 9. differential equations

જો એક વક્ર \( y=f(x) \) બિંદુ \( (1,-1)\)  માંથી પસાર થતો હોય અને વિકલ સમીકરણ \(y\left( {1 + xy} \right)dx = xdy\) ને સંતોષે ,તો \(f\left( { - \frac{1}{2}} \right) = \) . . . . . થાય. .

  1. A \(\frac{2}{5}\)
  2. B \(\frac{4}{5}\)
  3. C \( - \frac{2}{5}\)
  4. D \( - \frac{4}{5}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{4}{5}\)

Step-by-step Solution

Detailed explanation

Given differential equation \(\mathrm{ydx}+\mathrm{xy}^{2} \mathrm{d} \mathrm{x}=\mathrm{xdy}\) \(\Rightarrow \frac{\mathrm{xdy}-\mathrm{ydx}}{\mathrm{y}^{2}}=\mathrm{xdx}\)…
