RPL Programming Examples 2-31
! 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.
