Only a very short post today as it is Valentines day and I want to devote my time to my family.
I have put up on my website a Geogebra file that allows you to view 2 heart-shaped parametric curves. Which do you prefer?
The original Geogebra file is also available for download here.
Desmos have also produced some cool Math-o-grams including this very cool heart inspired Sierpinski triangle! I particularly like that you can see the underlying equations.
