The degree of the differential equation $\log \left(\frac{d y}{d x}\right)$ $\left(2 x+3 \frac{d y}{d x}\right)^2$ is
- 1
- 2
- 3
- not defined
Solution
$
\begin{aligned}
& \text {} \because \log \left(\frac{d y}{d x}\right)=\left(2 x+3 \frac{d y}{d x}\right)^2 \\
& \Rightarrow\left(\frac{d y}{d x}\right)-\frac{1}{2 !}\left(\frac{d y}{d x}\right)^2+\frac{1}{3 !}\left(\frac{d y}{d x}\right)^3-\ldots \\
& =4 x^2+3 \\
& \left(\frac{d y}{d x}\right)^2-12 x\left(\frac{d y}{d x}\right)
\end{aligned}
$
The order of the above differential equation is 1 and degree of the differential equation is undefined
