I have a very simple notation problem I cannot solve (because of my limited
knowledge of Mathematica).
Example -- an equation from physics:
f := a * t^2 / 2 - p == 0
Now I want to create the different forms of this equation, such as:
sqrt(2) * sqrt(p) / sqrt(a)
Okay, the correct general solution. What I really wanted was the limited
solution ( sqrt(2p/a) ). I know I need to say "assume all the variables are
>= 0", but I can't figure out how to express this.
I've tried applying a number of different constraints without success.
Hey -- I warned you. Simple problem. :)
