Hi!
I began to use Mathematica, and found out it is great.
But I happen to have a question during solving differential equtations.
Here's a problem.
y'_0(t) = -a * y_0(t) + b * y_1(t)
y'_1(t) = a * y_0(t) + (c*t-b) * y_1(t) --- (*)
^
This can be solvable mathematically, even some tedious work,
but when I use Mathematica, it can't solve it.
After some trial and error, I found out that 't' in (*)
is the problem - problem that mathematica doesn't give an answer,
it just shows the above equations as an answer.
So I wonder if this is the limit of Mathematica,
or is there any way to solve it?
I sincerely hope there's some way - because my work involves
a lot of Diffrential Equations.
Any reply would be appreciated.
James.
