For Valentines’s Day, February 14, I have created a series of graphs that outline the shape of a traditional heart.
If you are using a TI-83/84 or a TI-84 CE, I have created programs that when executed, will sketch out the shape of a heart. On the TI-84 CE it will be in color.
If you are using TI-Nspire, I have created a file that will not only sketch out the shape of a heart, but the file will also show the student (teacher) how this was accomplished.
Lines of code for the programs for the TI-83/84 and the TI-84CE are listed below. The actual programs can be downloaded from the links.
TI-84CE (color) version:
