RE: Proper use of Solve App
Do you see any problems if you enter any value other then "0" for your two guesses?

It seems to me the CAS fsolve command (which is what is being called in the solve app behind the scenes) is doing something strange when you put two guesses of 0 in. You can see this by typing this in the CAS screen.

fsolve([l = (w+10),(l*w) = 1200],[l,w])

Note that if you change that to a, b;

fsolve([a = (b+10),(a*b) = 1200],[a,b])

It works fine, and spits out the two results. If you store a float into the vars though of 0., using a:=0. b:=0. , you will start to see the misbehavior.

Store b:=.1, and suddenly it starts working again.


So I'd say put any number other then 0 in for a guess and it most likely will work. I think this might be something to go on Bernard's "list"...
