According to the shape of the heart, the same number of people are placed symmetrically in the middle of the heart, and cooperation can form the heart.

1. Heart-shaped stars have a special shape, which can arrange people's hearts according to their special edges and corners.

You can determine the important points (center point, highest point, etc.) first. ) in the heart of the site, and then make corresponding arcs along important points, so that people on both sides are evenly distributed.

3. Fill in the vacant position with people, and you can get the heart shape released by people.

Extended data:

The heart shape can be expressed by a mathematical equation:

1, polar coordinate equation

Horizontal direction: ρ=a( 1-cosθ) or ρ = a (1+cos θ) (a > 0);

Vertical direction: ρ=a( 1-sinθ) or ρ = a (1+sinθ) (a > 0)。

2. Cartesian coordinate equation

The expressions of the plane rectangular coordinate system equation of the heart line are x 2+y 2+a * x = a * sqrt (x 2+y 2) and x 2+y 2-a * x = a * sqrt (x 2+y 2) respectively.
