solving a hard Bernoulli differential equation

[@Ninja20704]

I laughed when you said “my favourite integration technique called ‘wouldn’t it be nice’” I had a question in my exam that required this exact idea and i was so thankful i watched your video on the 1 2 3 4 integral you mentioned.

hello, do you happen to know the video title, please?

Recipe for Riccati equation Pick a random functions p(x) and q(x) and u(x) Let u(x) be particular solution of Riccati equation Write Bernoulli equation with r=2 Substitute v(x)=y(x) - u(x) If we pick our favourite function for u(x) we can generate Riccati equation fe from this equation and such Riccati equation would not be difficult to solve

You don't need the substitution though. Instead with Bernoulli Equations like dy/dx+p(x)y=y^2 you can divide by y^2 and multiply by -1 to get -y^-2dy/dx -p(x)y^(-1)=-1. Then, e integral -p(x) dx becomes the integrating factor and you will get d/dx(IF*y^-1)= -1*IF. This works on all Bernoulli equations to my understanding, so substitution is not needed. I was able to adapt the method from a textbook that seemed to bizarrely multiply by 2 when there was y^2 and I figured out what was going on. You need to generate a product rule involving y^n* IF.

Nice :)

Not tanx + 1 again 😭
