Question
A Bernoulli differential equation is one of the form
dydx+P(x)y=Q(x)yn.dydx+P(x)y=Q(x)yn.
Observe that, if n=0n=0 or 11, the Bernoulli equation is linear. For other values of nn, the A Bernoulli differential equation is one of the form
dydx+P(x)y=Q(x)yn.dydx+P(x)y=Q(x)yn.
Observe that, if n=0n=0 or 11, the Bernoulli equation is linear. For other values of nn, the substitution u=y1−nu=y1−n transforms the Bernoulli equation into the linear equation
dudx+(1−n)P(x)u=(1−n)Q(x).dudx+(1−n)P(x)u=(1−n)Q(x).
Use an appropriate substitution to solve the equation
y′−(5/x)y=y^4/x^10,y′−((5/x)y)=y^4/x^13,
and find the solution that satisfies y(1)=1.y(1)=1.
