MATHEMAGIC 8: HEARTBEAT

How to draw a heart on a graphic calculator TI-84?

 

For about 15 years I have promoted the introduction
of the graphic calculator in the Flemish secondary schools for Texas Instruments.

In this function I wrote 3 cahiers (in Dutch) with worked out examples for T3 Flanders
(T3 = Teachers Teaching with Technology):

Cahier 1     Mathematiseren met functies in de derde graad

Cahier 12   Onderzoekscompetenties in de derde graad

Cahier 40   Wiskundige uitdagingen met de TI-84 Plus (CE-T) 

You can download these cahiers for free on

The area bounded by this cardioid (given by its polar equation) equals π.
