How to factor out the similar powers terms in Mathcad 6.0? Please see attached for a better explanation

Thanks a lot for the helps

The possibilities to influence the type of output of a symbolic transformation are unfortunately very limited.

I am afraid that you will not be able to achieve the type of representation you want.

You may want to try the symbolic keyword *collect*, if that still exists in Prime 6. Example:

And to get the coefficients of all powers of s in vector form, try *coeffs*.

Success!

Unfortunately using the original "G" from the provided sheet, both "collect" and "coeffs" return expressions too large to display.

At least with "coeffs" a workaround could be to assign the result to a variable and evaluate the elements of the vector singly:

Hi Luc,

Thanks for the helps. Looks like your version of Mathcad did it. It is able to factor out the terms. As Werner mentioned, using Collect and Coeffs in Mathcad 6.0 results in the expressions that are too high entropy and it is hard to understand what it means. Please see attached

What Mathcad version are you using Luc?

I am checking with Mathcad support on this and hope they have a solution.

The attachment is just a simple expression right now. My actual equation is much more complicate and it would be a nightmare if I have to do it manually

Thanks for all the helps
