Using Mathematical Formulas to Draw the Symbol of Love

It is interesting for us to see heart-like mathematical shapes. We can introduce an unlimited number of heart curves using basic functions. For instance, the cardioid is a historical example of a heart-shaped curve. Below are five heart-like images which I've created by trigonometric functions. I believe mathematics is an international culture. Therefore, I think mathematics can help us to promote love between nations.
