Mode Settings

These are the settings that can be used with setMode() and getMode(), with a brief explanation. The 'Number' field refers to an alternate string that can be used for compatibility with other language versions.

Tables are also given for the setGraph() and setTable() commands.

# Table for setMode() and getMode()

"Graph" "1" The type of equations that can be graphed Setting Number Meaning "FUNCTION" "1" Graphs functions of the form y(x) by connecting points (x,y(x)) for all x. "PARAMETRIC" "2" Graphs functions of the form x(t), y(t) by connecting points (x(t),y(t)) for a range of t. "POLAR" "3" Graphs functions r(θ) where θ is the angle with the x-axis and r is the radius. "SEQUENCE" "4" Graphs possibly recursive functions u(n) in several ways. "3D" "5" Graphs functions of the form z(x,y) on 3-dimensional x, y, and z axes. "DIFF EQUATIONS" "6" Graphs solutions and slope fields for simple differential equations. "FIX #" "1"-"13" Displays a fixed number of digits after the decimal, # can be 0 to 12. "FLOAT" "14" Equivalent to "FLOAT 12". "FLOAT #" "15"-"26" Displays up to # digits total, omitting final zeros after the decimal. # can be 1 to 12. "RADIAN" "1" Most common for mathematicians: a full circle is equal to 2π radians. "DEGREE" "2" Common for non-mathematicians: a full circle is equal to 360 degrees. "GRADIAN" "3" (Requires AMS 3.10) An uncommon format in which a full circle is equal to 400 gradians. "NORMAL" "1" Most numbers are displayed in the normal way; large numbers use scientific notation. "SCIENTIFIC" "2" All numbers are displayed as mantissa*10^exponent (E stands in place of *10^). "ENGINEERING" "3" Similar to scientific notation, except exponent must be a multiple of 3. "REAL" "1" The Non-real result error happens if the result of an expression is complex. "RECTANGULAR" "2" Complex numbers are written as x+yi. "POLAR" "3" Complex numbers are written as reθi. "RECTANGULAR" "1" Vectors are displayed just like any other matrix. "CYLINDRICAL" "2" Vectors are displayed in [r ∠ θ] or [r ∠ θ z] format. "SPHERICAL" "3" Vectors are displayed in [r ∠ θ] or [r ∠ θ ∠ φ] format. "OFF" "1" Pretty print is disabled: formulas are displayed the way they are typed. "ON" "2" Pretty print is enabled: formulas are displayed the way they would be on paper. "FULL" "1" The entire screen is devoted to one task. "TOP-BOTTOM" "2" The screen is split into top and bottom halves devoted to separate applications. "LEFT-RIGHT" "3" The screen is split into left and right halves. (Apart from the defaults: "Home", "Graph", etc. the apps depend on what's installed, and aren't numbered.) (Apart from the defaults: "Home", "Graph", etc. the apps depend on what's installed, and aren't numbered.) "1" "1" There is only one graphing mode. "2" "2" There are two graphing modes. (See the "Graph" setting for the options here — they are the same) "1:1" "1" The two parts are equal. "1:2" "2" The second part is twice the size of the first. "2:1" "3" The first part is twice the size of the second. "AUTO" "1" Exact results stay exact except to prevent overflow; floating-point numbers stay in floating-point. "EXACT" "2" All numbers are automatically converted to exact integers or fractions "APPROXIMATE" "3" All calculations are done in floating-point, as on the TI-83 series calculators. "DEC" "1" Integers are displayed in the usual (decimal) base, in their entirety. "HEX" "2" The lowest 32 bits of an integer are displayed in hexadecimal (base 16). "BIN" "3" The lowest 32 bits of an integer are displayed in binary (base 2). "OFF" "1" Applications are selected through a popup menu. "ON" "2" Applications are selected through a graphic interface.

# Table for setGraph()

"Coordinates" "1" The coordinate system used for recording the cursor's location Setting Number Meaning "RECT" "1" The standard (x,y) coordinates are displayed and stored to xc and yc. "POLAR" "2" The polar (r,θ) coordinates are displayed and stored to rc and θc (standard coordinates are also stored). "OFF" "3" No coordinates are displayed, although the standard (x,y) coordinates are still stored. "SEQ" "1" Different equations are graphed one after the other. "SIMUL" "2" Different equations are graphed simultaneously. "OFF" "1" The grid is not displayed. "ON" "2" The grid is displayed. "OFF" "1" The axes are not displayed. "ON" "2" The axes are displayed. "AXES" (3D mode) "2" The axes are displayed. "BOX" (3D mode) "3" A 3D box is displayed outside the graph. "OFF" "1" The cursor is not displayed. "ON" "2" The cursor is displayed. "OFF" "1" The axes aren't labeled. "ON" "2" The axes are labeled. "TIME" "1" Each sequence is graphed with n on the x-axis and ui(n) on the y-axis. "WEB" "2" A web diagram of one sequence is graphed. "Custom" "3" The variables for the x-axis and y-axis can be selected. "RK" "1" Runge-Kutta is used to estimate solutions. "EULER" "2" Euler's method is used to estimate solutions. "SLPFLD" "1" A slope field is displayed. "DIRFLD" "2" A directed slope field is displayed. "FLDOFF" "3" No field is displayed. "TIME" "1" yi(t) is plotted against t.

# Table for setTable()

"Graph <-> Table" "1" Source for automatic table values Setting Number Meaning "OFF" "1" Automatic table values are based on tblStart and Δtbl. "ON" "2" Automatic table values are the same as those used to graph the equation. "AUTO" "1" Use the automatic table values (as above) for the independent variable. "ASK" "2" Enter values for the independent variable manually, ignoring other table settings.
