Hi Haider, your equation is not an ordinary differential equation, but a so called delay differential equation. Although I have not tryed it, a package to numerically solve this type can be found at: http://library.wolfram.com/infocenter/MathSource/725/ You could also check: http://forums.wolfram.com/student-support/topics/4593 hope this helps, Daniel Haider Arafat wrote: > I am not able to use NDSolve to integrate a differential equation of the > form > > u''(t) + a u(t) == b u(t-tau); > u(0) == u0; > u'(0)==udot0; > > where tau, a, and b are all constants.
