Hi guys so here is the code (*Parameters*) tend = 100; Mu = 1; Rho = 2.62*10^-12 Exp[-(500000 - r[t] )/64500]; Rtet = Rearth + 500000 - r[t] ; ugc = 6.67*10^11; massEarth = 5.9721986*10^24; v =...
Hi, good day to you and Aaron here again. I recently have a problem when I'm trying to compute a huge matrix size and after 1 and a half day of running the simulation, this came out "SystemException[SparseArrayNormalLimit,Normal[SparseArray[ ,{...
Hi, guys I have a problem here on how should I add a condition for variable "A" as shown in the image highlighted in red under equation 4 (eq4). The condition I would like to set is that "A" equals "(b/m)p'[t] + (k/m)(p[t]-0.5) when "(p[t] >=...
Hmmm, not sure bout that but, here's the file attached regarding my problem. Hopefully you can help me out. Thanks a lot.
Hi guys, Aaron the short here and I have a long problem  with ODE's, I formed 3 equations dealing with 3 generalized coordinates for a lagrangian and the code is as below.[mcode]{A, L, p, mu, MM, MP, rm, rp, Eo, n} = {62.83*10^-6, 10000, 1140, ...
