I created a simple calculation of the oscillation of a pendulum in Mathcad 15 - it does not work. The calculation worked when I converted it to Prime 5. I can’t find a mistake - there is no time - my wife is calling to go for a walk in the park - the weather is very good. I hope that when I return from the walk, someone will find a mistake 😉
Solved! Go to Solution.
Thanks!
I forgot about this bug with not correct error message in Mathcad 15.
In Prime all is OK!
Yes, Mathcad always had problems when the highest derivate was not on the left hand side.
The second problem was that you forgot to strip the units from the constant of gravity g.
Its nice to see that Prime does not suffer from the problem with the highest derivative on the "wrong" side and of course its one of the few highly acclaimed improvements in Prime that odesolve can work with units.
