What have you done so far and where exactly you got stuck in the handling of Mathcad?

Attach please your sheet.

I guess this link, while 20 years old and using Mathcad 3 (!!), should help :http://www.users.csbsju.edu/~frioux/reprints/JCE1992pA240.pdf

Some other links which might be of interest, too:

But then, you sure can use Google yourself 😉

    Again a very unspecific question.

    What have you done so far to get acquainted with the software?

    You may start with the documentation you got, use a decent primer or get your hands on the help sheets which are installed along with the software. The help is also available online here http://www.ptc.com/cs/help/mathcad_hc/prime2_hc/
