cooldude832 Posted October 16, 2007 Share Posted October 16, 2007 Anyone Got any idea on how to accomplish this. I know I have to make a calculus library to back this for differentiation/integration, but my main idea was I wanted a system of solving burneoli equations.

cooldude832 Posted October 16, 2007 Author Share Posted October 16, 2007 sure, I can't spell. Almost linear equations in which the form of dy/dx + p(x)y = f(x)y^n where n is any integer >1 and then you make the substitution of u = y^1-n and then you supply the rest of the subsutitions and you should have a linear equation that you can solve by applying an Integrating factor to it that makes the left side of it be d/dy[i.F(P(x))y] and the right side can easily be solved via parts and or any other technique of integration. No not delaying specifically with fluids, but in general as a technique of solving almost linear first order equations.
