SUMMARY

The discussion focuses on solving the Bernoulli equation represented as (y^7 - 6x)y' + y = 0. Participants identify the need to rewrite the equation in the standard form y' + P(x)y = Q(x)y^n. The main challenge highlighted is the difficulty in manipulating the equation to achieve this form, with suggestions to consider the substitution x = x(y) and the relationship y' = 1/x'. This approach is essential for simplifying the problem and finding a solution.

Homework Statement


I think this is a bernoulli equation in disguise
(y^7-6x)y'+y=0

Homework Equations


I'm having trouble putting it in the form of y'+P(x)y=Q(x)y^n


The Attempt at a Solution


I've tried to divide out (y^7-6x) as well as some other alebraic manipulation but i keep getting stuck. Any advice?

Try writing it in terms of [itex]x = x(y)[/itex] and using:

[tex] y' = \frac{1}{x'}[/tex]
