WebIn practice, many problems are modelled with coupled variables, making the corresponding equation multi-dimensional. Multi-dimensional equations also arise when the starting equations contain higher-order derivatives. They can then be converted to a system of first-order differential equations. WebI've been working with sympy and scipy, but can't find or figure out how to solve a system of coupled differential equations (non-linear, first-order). So is there any way to solve …
