Expression as a variable?

  • February 11, 2012

There are cases where a value in an equation may be assigned to an expression rather than a single variable.

For example: (e^alpha)/k = 3

Is there a way to define such an expression so it can be carried "as is" in an equation without having to fist substitute it with a single variable?

Thank you.

Whaoh! Thanks.I had looked up and down the manual (2001) and even now that you pointed out the way, I still cannot locate it in the manual! But it works fine with 2001.

Coincidentally, this was precisely for a chemistry prob that I was looking for the feature!

Maybe you also have similar magic strokes for "average" ( a bar over the variable name) and "star" as in p* for instance?

With star no problem:

ne general solution of this problem - the using picture as variable names. I do so on Mathcad Server:
