Question
Form the differential equation by eliminating arbitrary constants from the relation
bx + ay = ab.
Solution
Given relation is
bx + ay = ab
Differentiating w.r.t. x, we get
`b + a dy/dx = 0`
Again, differentiating w.r.t. x, we get
`a (d^2y)/dx^2 = 0`
∴ `(d^2y)/dx^2 = 0`, which is the required differential equation.
