Equation app errors
When you see this It means this:
message:
Infinitely Many An infinite number of solutions for
Solutions simultaneous linear equations.
No Solution No solution for simultaneous linear
equations.
No Variable No variable within a
equation.
Graph&Table, Recursion, Dyna Graph, Conic Graphs app errors
When you see this It means this:
message:
Range ERROR View Window range settings exceeded
when a graph is drawn.
Circular ERROR The two recursion formulas that were input
cross-reference each other.
No Variable No variable specified within a function
being used for dynamic graphing in the
Dyna Graph app.
No item is selected Attempting to draw a graph or create a
table while there is no data selected.
Equation does not You attempted to execute a Modify
have a parameter. function operation while no expression that
contains a variable is selected.
Condition ERROR You attempted to execute a Modify
operation while multiple expressions
containing variables are selected.
Expression in use Attempting to copy the expression of a
graph while Modify is running to an area
where an expression that is being used for
graphing is located.
Too Many Variables Attempting to execute the Modify function
using an expression with more than five
variables.
Invalid Graph Type • You selected one of the mathematical

function expressions ((a) through (d)) in
the Graph&Table app and attempted to
create a number table.
(a) Function expression containing
alpha variables, with specification
of values assigned to the variables
(Example: y =Ax − 1,[A=1,2,3])
(b) Function expression containing a list
(Example: y ={1,2,3} x )
(c) Function expression with a range of
variables (Example: y = x ,[0,2])
So you need to do this:
Input an equation that includes a variable.
So you need to do this:
Redraw using the proper View Window
settings.
Edit the recursion formulas to resolve
the cross-referencing. For details, see the
Note under
formula" (page
Specify a variable for the graph function.
Select data and try again.
Select at least one and only one expression
that contains a variable.
Select a different area and try again.
Change the expression so it contains no
more than five variables.
Choose another type of function and try
again.
