gc:fillArc is a function that is part of gc (Graphics Context).
Draws a color-filled arc in the rectangle with upper left corner (x,y) and pixel width and height. The arc is drawn beginning at startAngle degrees and ending at endAngle.
Zero degrees points to the right and 90 degrees points up (standard mathematical practice but worth mentioning since the y axis is inverted).
This has been introduced in TI-Nspire OS 3.0 (Changes).

Example
gc:fillArc(10, 10, 20, 30, 0, 120)Good to know
To draw a circle, the width and height must be equal length and the start and end angles must be 0 and 360. If width and height are different lengths, this routine will draw an oval.
