I have a question regarding solving differential equations, in particular systems of differential equations, that involve vectors. For example, my particular problem is attached to this post (solution variables are alpha and Ac). While I'm no stranger to either vectors or solving ODEs, I'm not particularly sure how to go about solving a system like this when it involves cross -products, differentiation, and the like all at once. Does anyone have any tips on a solution method? I can handle either numerical or analytical solutions, I'm just rather confused by all the cross products in this problem.
