Hi. I have the problem presented in the attachement. I need to replace the value of the determinant of the second expression with B, to make it simpler. I've tried with "explicit, B" but it doesen't work. How do i do that? Thank you

He has alreaday asked the same question here: http://communities.ptc.com/message/261653#261653

For reasons unknown to us he wants Mathcad to display something like

which I guess is demanding too much.

Can't see your file at the moment but the mathematical term for replacement is substitution. Mathcad has that built in. Use the 'substitute' symbolic keyword with argument {determinant}=B.

Success!

It is possible, if you tell Mathcad what you want it to give you. With:MatrixAlgebra.png
