How do you do (a) and (b)?
bernoulli’s equation is an equation of the form y ′ = a(t)y + f(t)y n , where n can't be 0 or 1.
(a) using the substitution z = y 1−n , 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 xy′ + y = x^4 y^3
