SUMMARY

The discussion centers on solving the Bernoulli differential equation represented by the equation 3y²y' + y³ = e^(-x). To transform this into a standard Bernoulli form, one must divide the entire equation by 3y², resulting in y' + (1/3)y = (1/3)e^(-x). This allows for the application of Bernoulli's method to find a solution. The key takeaway is the necessity of recognizing the form and applying the appropriate transformation for effective resolution.

The Problem:

3y2y' + y3 = e-x

I think maybe I'm supposed to use something to do with the Bernoulli stuff, but I'm not sure. I've tried to figure it out for a while now and I'm stuck.

Thanks for any help you can give.

It's in the form of a Bernoulli DE if you divide everything by 3y^2.
