I'm attempting to solve a simple equation in terms of known variables
and then calculate the value of the unknown by applying the known. For
example, given a^2+b^2=c^2, a and c are the known variables with values
of 3 and 5. It seemed like the following would do the trick:
e1: a^2+b^2=c^2;
apply(rhs(first(solve (e1, b))), [3, 5]);
expecting to get 4 as an answer but instead get an error but don't yet
know enough of maxima to troubleshoot it.
Thanks,
Phil
