Teaching DSSSB TGT Mock Test 2025 Mathematics Differential Equations Solution of Differential Equations
The solution of the differential equation \(\rm\frac{dy}{dx}+\frac{2xy}{1+x^2}=\frac{1}{\left(1+x^2\right)^2}\) is :
1
y(1 + x2) = c + tan–1x
2
\(\rm\frac{y}{1+x^2}\) = c + tan−1x
3
y log (1 + x2) = c + tan–1x
4
y (1 + x2) = c + sin–1x
