Thanks!

But an error we have - y1 is red!

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

Do you know them?

I don't know.

No! Честное слово!

[vlehner]

how do you know that there are 9 ones left?

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

[vlehner]

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...

[vlehner]

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!

[ValeryOchkov]

I think it is a bug in Mathcad 15..

Oder in my  Kopf.

[ValeryOchkov]

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

Sorry, not animation thru Mathcad 15 or me Kopf bug but frames of animation created in Prime

[vlehner]

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!
