Question
Sometimes it is possible to solve a nonlinear equation by making a change of the dependent variable that converts it into a linear
equation. The most important such equation has the form
y' + p(t)y = q(t)y"
and is called Bernoulli's equation after Jakob Bernoulli.
If n # 0, 1, then the substitution v = yl-" reduces Bernoulli's equation to a linear equation.
Solve the given Bernoulli equation by using this substitution.
