Numeric Solver 671
• If you refer to a previously defined
function, any variables used as
arguments in the function call are listed,
not the variables used to define
the function.
• If the equation contains a system variable
(
xmin, xmax, etc.), that variable is not
listed. The solver uses the system
variable’s existing value.
Note: You cannot solve for a system
variable other than exp. Also, if the
equation contains a system variable, you
cannot use … to graph.
• Although you can use a system variable
in the equation, an error occurs if you use
… to graph the solution.
If f(a,b) was defined
previously as
‡(a^2+b^2) and your
equation contains
f(x,y), then x and y are
listed, not a and b.
In the standard viewing
window, xmax=10.
