MuPad: Heart in 3D
This is not mathematics. I just found an equation so that we can draw a heart in 3D. Indeed, the following equation $latex \displaystyle {\left( {{x^2} + \frac{9}{4}{y^2} + {z^2} – 1} \right)…

예전에 하트 곡선을 올렸는데 오늘은 하트 곡면을 보았다.
$$\bigg(x^2 +\frac{9}{4}y^2 +z^2 -1\bigg)^3 -x^2 z^3 -\frac{9}{80}y^2 z^3 =0$$
