Question

Q.8. Find the order of differential equation of all conics whose centre lies at origin.

Answer 1

Dear student

$$\begin{gathered} \mathrm{As}\mathrm{centre}\mathrm{is}\mathrm{origin},\mathrm{equation}\mathrm{of}\mathrm{ellipse}\mathrm{can}\mathrm{be} \\ \frac{{\mathrm{x}}^2}{{\mathrm{a}}^2}+\frac{{\mathrm{y}}^2}{{\mathrm{b}}^2}=1 \\ \mathrm{Number}\mathrm{of}\mathrm{parameter}=2 \\ \mathrm{So},\mathrm{its}\mathrm{order}=2 \end{gathered}$$
