Understanding Test Mode Restrictions

By default, all restrictions are disabled when you enter a Test Mode session with the exception of Numerical Solver and Sliders.

• Enabling a restriction allows its associated features to be used during the session.
• Disabling a restriction disables or limits its associated features during the session.

When you choose to limit geometry functions, all items on the Measurement, Construction, and Transformation menus are disabled.

• You cannot move any function or conic in Graphs or Geometry. For example, if you have graphed y=x3, you can select the function but you cannot move or manipulate it by dragging.
• You cannot access the attribute that toggles the displayed form of a second degree polynomial relation between Standard and Expanded.
• Disabling function and conic grab and move does not apply to lines and functions in Data & Statistics.
• Disabling function grab and move does not restrict sliders in the Graphs and Geometry applications.
• You can still grab the coordinate plane and move it around.

When vector functions are disabled, students cannot calculate the following functions:

• Unit vector [unitV(]
• Cross product [crossP(]
• Dot product [dotP(]
• Eigenvector [eigVc(]
• Eigenvalue [eigVl(]

The isPrime( function determines if a number is a prime number (a whole number greater than two that is evenly divisible only by itself and one). Disabling this function prevents students from selecting the isPrime( command in the Catalog and from selecting Test > IsPrime in Math Operators. If a student manually enters the isPrime( function, submitting the expression results in an error message.

The Differential Equation graph type is disabled in the Graphs and Geometry applications. Users cannot manually type and graph a differential equation.

Related math functions rk23(, euler(, and deSolve( are also disabled.

When inequality graphing is disabled, students cannot graph inequalities with <, >, ≤, and ≥ or grab and drag inequalities to a graph in the Graphs and Geometry applications.

When this feature is disabled, students cannot use the 3D Graphing view.

When these features are disabled, students cannot graph equations in terms of x = ay + c or ax + by = c. Conic templates are not available, and students cannot analyze conics or graph the geometric conic of an ellipse, parabola, hyperbola, or conic by five points.

Disabling trigonometric functions prevents students from using the following functions in calculations and graphing.

csc

sec

cot

csc-1, arccsc

sec-1, arcsec

cot-1, arccot

csch

sech

coth

csch-1, arccsch

sech-1, arcsech

coth-1, arccoth
• Attempting to evaluate any of these functions results in an error message.
• Students cannot select the disabled functions from the Catalog.

Students cannot use the logbx (convert to logbase) and log(a, b) commands and templates, including logbx templates.

• Only calculations in log10 format are accepted.
• If a student manually enters log(a,b) or >logbase( into an expression, attempting to evaluate the expression results in an error message.
• Students are allowed to enter log(a), log(a,10), and log(a,10.).

Students are also prevented from using summation functions and templates. The ∑( and sumSeq( functions are disabled.

The polyRoots(, cPolyRoots(, solve(, simult(, zeros(, and cZeros( functions are disabled. Attempting to evaluate any of these functions results in an error message.

Note: When the polynomial tools are disabled, students cannot use Find Roots of Polynomial, Real Roots of Polynomial, or Complex Roots of Polynomial.

The linSolve( and simult( functions are disabled in menus and in the Catalog. Attempting to evaluate either of these functions results in an error message.

The nSolve( is disabled in menus and in the Catalog. Attempting to evaluate either of these functions results in an error message.

When this feature is disabled, students cannot insert or create sliders in the Graphs, Geometry, Data & Statistics, and Notes applications.
