$px2+$qy2=$r
If you have previously defined the parameters $p, $q and $r, this might be rendered as
In FX Equation, this might look like this
FX Equation has replaced the three parameters with the three numbers. So far, so good, but this is not very "dynamic". Things begin to get dynamic when we start using the different types of parameters. |
