I'm trying to use Mathcad to solve a series of equations. I keep getting the error message "This variable is undefined" Any tips?

it appears that there are at least 3 issues with the equations in the given statement.

If you make a little space above the 'given' you can copy the LHS & RHS of each equation there & use the evaluation = to inspect the result.

For the first equation RHS the A.t( assumes that it is a function; Add a * to fix it

For the 2nd RHS the same applies for the A.s(.

For the 2nd equation LHS the 1st term has units of W/m, the second term has units of W and the RHS also has units of W.

There is an issue here, but I can't advise what it needs to fix it.

Hope this helps

Andy
