Form the differential equation of the family of circles having centers on the x-axis and radius unity.
Equation of the family of circles having centers on the x-axis and radius unity can be represented by
(x - a)2+(y)2= 1, where a is an arbitrary constants.
(1)
Differentiating the above equation with respect to x on both sides, we have,
Substituting the value of a in equation (1)
This is the required differential equation.
