To move the trace cursor to any valid T value on the
current function, enter the number. When you enter the
first digit, a T= prompt and the number you entered are
displayed in the bottom-left corner of the screen. You can
enter an expression at the T= prompt. The value must be
valid for the current viewing window. When you have
completed the entry, press Í to move the cursor.
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 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.
