defining earlier

[kenan2]

Yes you can, but you should be sure to (re-)define variables whose name you (re-)use.

Mathcad looks above and to the right for any definition of a variable that you use. If it's undefined, the numeric processor will complain. The symbolic processor can deal with undefined variables, and also with variables defined in terms of undefined variable.

Using Prime you can also undefine variables.

The same goes for functions...

Success!

As far as I remember you are using Prime.

Here you are able to clear variables using the clear command.

You could also clear a variable for symbolic use only by using clear.sym

See the simple example below
