Question
25. Bernoulli's equation is an equation of the form
y' = a(t)y+ f(t)y",
where n + 0 or 1. Bernoulli's equation is nonlinear and cannot be solved by the
techniques that we have used to solve first order linear equations.
a. Using the substitution z = y-", show that we can transform Bernoulli's
equation into the linear equation
z' = (1 – n)a(t)z+(1 – n) f(t).
b. Solve the equation æy' + y = x*y°.
