Sintp (Converting A Plot To A Graphics Object); Techniques Used In Sintp - HP 48gII Advanced User's Reference Manual

SETTS superimposes plots of successive Taylor's polynomials on the sine curve plot from SINTP, and saves
!
the resulting graphics objects in a list.
TSA uses the ANIMATE command to display in succession each graphics object from the list built in SETTS.

SINTP (Converting a Plot to a Graphics Object)

SINTP draws a sine curve, returns the plot to the stack as a graphics object, and stores that graphics object in a
variable. Make sure your calculator is in Radians mode.

Techniques used in SINTP

Programmatic use of PLOT commands. SINTP uses PLOT commands to build and display a graphics
!
object.

SINTP is demonstrated in the program TSA.
Comments:
Stores the expression for sin
x in EQ.
Sets the plot type and x- and
y-axis display ranges.
Erases PICT, then plots the
expression.
Recalls the resultant graphics
object and stores it in SINT.
Stores the program in
SINTP.
