TI-83 Plus Parametric Graphing 165
ZOOM
ZOOM operations in Par graphing work the same as in Func graphing.
Only the X (Xmin, Xmax, and Xscl) and Y (Ymin, Ymax, and Yscl) window
variables are affected.
The T window variables (Tmin, Tmax, and Tstep) are only affected when
you select ZStandard. The VARS ZOOM secondary menu ZT/Zq items
1:ZTmin, 2:ZTmax, and 3:ZTstep are the zoom memory variables for Par
graphing.
CALC
CALC operations in Par graphing work the same as in Func graphing. The
CALCULATE menu items available in Par graphing are 1:value, 2:dy/dx,
3:dy/dt, and 4:dx/dt.
