# Find the Differential Equation of the Family of Concentric Circles X^2 + Y^2 = A^2 - ISC (Commerce) Class 12 - Mathematics

ConceptGeneral and Particular Solutions of a Differential Equation

#### Question

Find the differential equation of the family of concentric circles x^2 + y^2 = a^2

#### Solution

Finally of concentric circle is x^2 + y^2 = a^2

∴DDifferential w.r.t x

2x + 2y dy/dx = 0

:. y dy/dx + x = 0

Is there an error in this question or solution?
