Question

Form a differential equation representing the given family of curves by eliminating arbitrary constants a and b.

y = e2x (a + bx)

Advertisements

Solution

y = e2x (a + bx) ...(1)

Differentiating both sides with respect to x, we get:

This is the required differential equation of the given curve.
