Hello to everyone here, I am trying to find the root of the next equation using Newton method: http://www.wolframalpha.com/input/?i=d%2Fdx%28du%2Fdx%29+%3D+%28-3%2F%28k1%29[x]%29*%28k4[x]-%28k2[x]%2Bk3[x]%29*u^%281%2F3%29%29+*%28%28du%2Fdx%29^%282%2F3%29%29 which has 2 boundary conditions (u(x=0)=0, u(x=n(max) = m (constant)) ...
Please, do someone knows if it is possible to solve this nth nonlinear second-order differential equation with sympy? (1D - x(1,n) , u(x), k1-k4 calculated on each x gridpoint). If I will use Central differencing to "simplify" it. Could be possible then to use sympy to help me to solve it ? ( system nth equations) How to calculate the Jacobi in this case for the Newton method? Do you know or see somewhere any relative example ? Please, any help will be more than welcome, Kas -- You received this message because you are subscribed to the Google Groups "sympy" group.
