Equation of the family of curves, y²=m(a²-x²), where a and m are parameters.

Differentiating the above equation with respect to x on both sides, we have,

(1)

Differentiating the above equation with respect to x on both sides,

(2)

From equations (1) and (2),

This is the required differential equation.
