Error In Dsolve Numeric Process_input
wrong with this differential equation, since maple can't solve it?? Edit Posted: December 16 2013 by Anna L 5 1 What is wrong??? restart;with(DEtools); with(plots);epsilon := 'epsilon'; epsilon := 0.3e-1;h := .75;p := 2;q := 0.6e-2; sol := dsolve([[epsilon*(diff(x(t), t)) = x(t)+y(t)-q*x(t)^2-x(t)*y(t), diff(y(t), t) = h*z(t)-y(t)-x(t)*y(t), p*(diff(z(t), t)) = x(t)-z(t)], [x(0) = 100, y(0) = 1, z(0) = 10]], type = numeric);%;Error, (in dsolve/numeric/process_input) system must be entered as a set/list of expressions/equations differential_equation dsolve + Manage Tags Short words that describe your content.

dsolve/numeric/process_input) system must be entered as a set/list of expressions/equations Edit Posted: May 31 2015 by GuilhermeG 10 1 I can't solve this problem, can someone explain me whats worng and how to fix it, here is what i've done: with(plots);with(DEtools);sist := diff(x1(t), t) = -4*x1(t)+x2(t), diff(x2(t), t) = -x1(t)+7*x2(t); d d --- x1(t) = -4 x1(t) + x2(t), --- x2(t) = -x1(t) + 7 x2(t) dt dt condi := [x1(0) = 0, x2(0) = 3], [x1(0) = 2, x2(0) = 1], [x1(0) = 7, x2(0) = 9]; [x1(0) = 0, http://www.mapleprimes.com/questions/200508-What-Is-Wrong-With-This-Differential x2(0) = 3], [x1(0) = 2, x2(0) = 1], [x1(0) = 7, x2(0) = 9]for i to 3 do sol[i] := dsolve({sist, condi[i]}, {x1(t), x2(t)}, numeric); gra := odeplot(sol[i], [x1(t), t], t = -1 .. 1); display(gra) end do; student solve problem error_message + Manage Tags Short words that describe your content.
