I'm practicing with matrices in Maple, but I have a question. My question is, how do I set up the differential equation system on matrix form x '(t) = Ax (t) + B?

Here are the equations:

x'₁(t) = x₁(t) - x₂(t) - 3

x'2(t) = 12x₁(t) - 8x₂(t) + 4

I've been looking around for some help sources, but the only one I could find is this. I tried to set it up like that, but didn't work, it gave me an error.

How should I set it up (using Maple commands)?

Hi again friends. I simply can't get the command to work. My task is to dsolve the differential equation numerically, by using dsolve which has an option called numeric. I need to use the numeric and odeplot command to plot the numerical solution for f(t) for the timeinterval from 0 to 600 s.

So I searched and found this link: http://www.maplesoft.com/support/help/Maple/view.aspx?path=plots/odeplot

The example in the page was useful, I followed the steps, but I keep get this error-repport:

Hi everyone, I'm having a bit of trouble using the dsolve () command in maple, it keeps coming up with error messages.

My assignment is to find the first order differential equation of T_ovn(t), and then I know that you have to define it and then dsolve the definition.

The problem is, that what am I doing wrong?
