How do I graph a heart shape on a TI-84 graphing calculator???

Question

Please help :)

Answer 1

A cardioid can be represented by plotting a graph of either (x^2 + y^2 − 1)^3 = x^2y^3 or, in polar form, r = 1 − sin(θ)

Answer 2

The standard equation of a cardiod (heart shape) is best written in polar coordinates:

r = 2a(1+ cosθ).

For each value of the constant a you will get a slightly different heart shape, thinner or wider. You really don't want to go into the cartesian form if you can avoid it.
