Thanks!

But an error we have - y1 is red!

The First difference was find - let find more 9 ones.

No - it is an analog of old visual game - see please pictures with cows.

What about Units in MC15?

maybe there is a problem with the solver.

Units are switch off: m=1 s=1 etc

We play this game when see on one page in book and on the screen - where are differences!

A program in book is OK but on the screen - errors.

I would like to create animations - but...

sorry,

I believe the error search remains a mystery for me today.
I have not done anything in MC15 for too long.

Mystery by me too.

I have converted the Mathcad 15 sheet with an error into Prime - no error. See the attach.

I go to bet. УТРО ВЕЧЕРА МУРЕНЕЕ!

I think it is a bug in Mathcad 15..

Oder in my  Kopf.

Sorry - not animation but frames of animation! (bug in Mathcad 15 or in my Kopf)

Good morning Valery!

I have changed equations in MC15 like this:

Then i converted the file into Prime and i got no error!

Now that's ok for me but anyway it is all very strange.

A picture in attach for Werner!

Animation of moving the point 0 without air resistance.

This pendulum has a period 15.37... sec!
