Result
Replots the graph using the window variables of the graph
that was displayed before you executed the last ZOOM
instruction.
Displays the portion of the graph that is in quadrant 1.
Adjusts the X or Y window settings so that each pixel
represents an equal width and height in the coordinate
system, and updates the viewing window.
Replots the functions immediately, updating the window
variables to the default values.
Performs a z test with frequency freqlist. alternative=
alternative=0 is ƒ ; alternative=1 is >. drawflag=1 draws
results; drawflag=0 calculates results.
Performs a z test. alternative=
alternative=1 is >. drawflag=1 draws results; drawflag=0
calculates results.
Replots the functions immediately, updating the window
variables to preset values for plotting trig functions.
Returns factorial of value.
Returns factorial of list elements.
Interprets value as degrees; designates degrees in DMS
format.
Interprets angle as radians.
Returns a matrix in which each element (row, column) is
swapped with the corresponding element (column, row) of
matrix.
th
Returns x root of value.
th
Returns x root of list elements.
L 1 is <;
1 is <; alternative=0 is
