We spent the first hour bringing everyone up to speed on the TI-Nspire (screencasts of Nspire skills will be posted). We then tackled the following problem:

Drag points B or C around the circle, and observe the locus of the plotted point ( central angle, chord length ).

Drag points B or C around the circle, and observe the locus of the plotted point

( central angle, chord length ).What is an equation that describes the locus?
