Function Graphing 4-17
ZDECIMAL replots the functions immediately, updates the
Window variables to preset values that set @X and @Y equal to
.1, and defines the X and Y value of each pixel as one decimal.
XMIN = L3.1 YMIN = L2.3
XMAX = 3.1 YMAX = 2.3
XSCL = 1 YSCL = 1
ZSQUARE replots the functions immediately, redefining the
window based on the current Window variables, but adjusted
in only one direction so that @X=@Y. This makes the graph of a
circle look like a circle. XSCL and YSCL remain unchanged.
The midpoint of the current graph (not the intersection of the
axes) becomes the midpoint of the new graph.
ZSTANDARD replots the functions immediately, updating the
Window variables to the standard values:
XMIN = L10 YMIN = L10
XMAX = 10 YMAX = 10
XSCL = 1 YSCL = 1
ZTRIG replots the functions immediately, updating the
Window variables to preset values appropriate for plotting trig
functions. In RADIAN mode, these are:
XMIN = L(31/12)p (L8.115781..) YMIN = L2 (L2)
XMAX = (31/12)p (8.1157810..) YMAX = 2 (2 )
XSCL = (p/2) (1.5707963..) YSCL = 1 (1)
