ZoomOut
Display the Graph screen, pauses so that a
zoom center point can be set, then updates the
viewing window. The zoom magnitude depends
on the Zoom factors xFact and yFact in 2D
graph modes, and on xFact, yFact and zFact in
3D mode.
ZoomPrev
Display the Graph screen and update the
viewing window with the settings before the
previous zoom.
ZoomRcl
Display the Graph screen and update the
viewing window with the settings stored with
ZoomSto.
ZoomSqr
Display the Graph screen and adjust the x or y
window settings so that each pixel represents
an equal width and height in the coordinate
system, then update the viewing window. In 3D
mode, lengthen the shortest two axes to equal
the longest axis.
ZoomStd
Set the Window variables to the following
standard values, then update the viewing
window.
Function graphing:
x:[-10,10,1], y:[-10,10,1], xres = 2
Parametric graphing:
t:[0,2Œ,Œ/24], x:[-10,10,1], y:[-10,10,1]
Polar graphing:
θ:[0,2Œ,Œ/24], x:[-10,10,1], y:[-10,10,1]
Sequence graphing:
x:[-10,10,1], y:[-10,10,1]
nmin=1, nmax=10, plotStrt=1, plotStep=1
3D graphing:
x:[-10,10,14], y:[-10,10,14], z[-10,10]
eyeθ°=20, eyeφ°=70, eyeψ°=0, ncontour=5
Differential equations graphing:
t:[0,10,.1,0], x:[-1,10,1], y:[-10,10,1]
ncurves=0, Estep=1, diftol=.001, fldres=14,
dtime=0
ZoomSto
Store the current Window settings in Zoom
memory. Use ZoomRcl to restore the settings.
ZoomTrig
Display the Graph screen, set x = Œ/24, xscl =
Œ/2, center the origin, set the y settings to
[-4,4,.5] and update the viewing window.
+ (add)
expr1 + expr2
Return the sum of expr1 and expr2
list1 + list2
matrix1 + matrix2
Return list or matrix whose elements are the
sum of the corresponding elements. Argument
dimensions must be equal.
expr + list
list + expr
Return list whos elements are the sum of the list
elements and expr.
expr + matrix
matrix + expr
Return matrix with expr added to each diagonal
element of square matrix. Use .+ (dot plus) to
add an expression to each element.
- (subtract)
expr1 - expr2
Return expr1 - expr2
list1 - list2
matrix1 - matrix2
Return list or matrix whose elements are the
elements of list2 (or matrix2) subtracted from
the corresponding elements of list1 (or matrix1).
Argument dimensions must be equal.
expr - list
list - expr
Return list where each element is each list
element subtracted from expr, or expr
subtracted from each list element.
expr - matrix
Return matrix: (expr * identityMatrix) - matrix
matrix must be square.
matrix - expr
Return matrix: matrix - (expr * identityMatrix)
matrix must be square.
(Note: use .- (dot minus) to subtract an
expression from each element.)
