Why Maple gives different looking solution when calling
? Both solution are actually correct. But look different. Here is an example
diff(x(t),t) = 2*x(t)-z(t),
diff(y(t),t) = 2*y(t)+z(t),
Notice the difference:
In first case, the x(t) and y(t) solutions have 2 constants of integrations, and in the second case, they have 3 constants of integration.
If we solve this using the matrix exponential method, the solution comes out to match the first one:
Again, both solution verify to 0, using odetest, and I assume now it is correct (have no reason to think odetest is not correct).
But I'd like to understand more why when passing the unknowns to dsolve, the solution comes out different looking (3 constants of integrations, vs. two in this case). Should the solution be the same looking in both cases?
This came out, since I thought my solution was wrong, since it did not look like Maple's.
