A question for the Mathcad historians

What Mathcad version and year did Odesolve first appear? This is not a test.

This is not a test.

That's a relief, because I would fail

Thanks Valery. I saw a set of problems solved prio to that and I wondered why odesolve hadn't been used, then I suspected that it may not have been available.

You welcome!

Mathcad 2000 with odesolve can solve only one ODE- a Cauchy and boundary problems.

Mathcad 2001 can solve a system of ODEs too - but only a Cauchy problem.

But a boundary problem of ODEs with big error! Mathcad 15 and Mathcad Prime too
