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

વક્રનું સમીકરણ મેળવો કે જે ઉગમબિંદુ માંથી પસાર થાય છે અને વિકલ સમીકરણ \(\left( {1 + {x^2}} \right)\,\frac{{dy}}{{dx}} + 2xy = 4{x^2}\) નું સમાધાન કરે છે .

  1. A \((1 +x^2)\,y = x^3\)
  2. B \(3(1 + x^2 )\,y = 2x^3\)
  3. C \((1 +x^2)\,y = 3x^3\)
  4. D \(3(1 + x^2 )\,y = 4x^3\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(3(1 + x^2 )\,y = 4x^3\)

Step-by-step Solution

Detailed explanation

Given differential equation is \(\left(1+x^{2}\right) \frac{d y}{d x}+2 x y=4 x^{2}\) \(\Rightarrow \frac{d y}{d x}+\left(\frac{2 x}{1+x^{2}}\right) y=\frac{4 x^{2}}{1+x^{2}}\) This is linear diff. equation I.F…
