I'm trying to use Mathcad to solve a series of equations. I keep getting the error message "This variable is undefined" Any tips?
Solved! Go to Solution.
1) You forgot to type multiplication dots when calculating A.t * (....). If you write A.t(...) then A.t is interpreted as function.
2) You have a unit mismatch in your second equation. The first summand has to be multiplied by a length (I had simply multiplied by 1m which sure is not correct)

Thank you! Very helpful.
It intrigued me that your first solve block worked but the second one didn't. I found two things from Werner's unit balance:
