Hello, Currently, I migrate my Maple Code to Mathematica code. On a part linked to linearization, I meet some difficulties. In fact, i try to linearize some differential equations around an equilibrium position. The linearization is made with Taylor expansion at the fist order. Unfortunately, i did…

This article in the Wolfram Library describes solving nonlinear boundary value problems by linearization. Iterative Solution of Highly Nonlinear Boundary Value Problems -- from... Nonlinear boundary value differential equations are usually solved with the "shooting method". In this tec…

Thank you for your information. I tried to apply the function lin[] described in your link but I didn’t manage to obtain the good results. I probably don’t use it correctly. May you specify me which quantities you enter for the variables noms ? I believed that it was ye (equilibrium position) + d…

Here my code, to help for troubleshouting Equation Psi eq? = (A*cos[?[t]]^2 - C*cos[?[t]]^2 + C)*[???][t] + (-2*A*sin[?[t]]*cos[?[t]] + 2*C*sin[?[t]]*cos[?[t]])* Derivative[1][?][t]* Derivative[1][?][t] + C*cos[?[t]]*Derivative[1][?][t]*? == Subscript[m, 3]*g*L*sin[?[t]]*cos…
