Cannot do the "find" command with "undefined variable" ? http://peecee.dk/upload/view/363439 As you can see, i have to make I_1:=r. I cannot directly write find(I_1,I_2,I_3)→ It will not do that. Why is that, and is it possible to force it? I cannot see the difference between using "I_1" and "r" but mathcad can :) And better yet, get it to write separately: "I_1=1.132 A" <--- That would be awesome! Because my math teacher will only accept "bold" or double underlined numbers as results. Is it possible to get mathcad to state all the intermediate results between the equations and the final result?
