Solve
The Solve aplet will solve an equation or an expression for its
unknown variable.
You define an equation or expression in
Symbolic view, then supply values for all of the variables
except one
in Numeric view. Then Solve will find the
remaining unknown.
As a simple example, consider the equation
force = mass x acceleration
(that
is,
f
=
m
*
a
) in
the Solve
Symbolic view.
