What is mathematics for the 2022 Winter Olympics?
The mathematics of the 2022 Winter Olympics is as follows:

1, graphics in the Winter Olympics

Axisymmetric and Centrally Symmetric Winter Olympics medals are circular, the five rings of the Winter Olympics are axisymmetric figures composed of five circles, and the snowflake guide card is centrosymmetric.

2. ski jumping

Take the third jump of Princess Gu Ailing, a parabolic frog, as an example. The speed assisted by skaters can reach 24 meters per second. When the skater slides, we will see a beautiful parabola whose trajectory can be abstracted as a quadratic function image. What is the maximum height of the skater from the ground?

3. Single cycle and elimination system

There are 10 teams participating in the curling mixed doubles competition in the Winter Olympics.

The first part is a single round robin, and each team needs to compete with other teams; The second part is the knockout stage. In the first part, the four teams with the highest total score participate in the final, and the losing side of both sides is eliminated directly, and the winning side is promoted directly. How many games can a * * * play?

4. Ski jumping trajectory: parabola

Take platform skiing as an example, the speed assisted by the skater can reach 24m/s, and we will see a beautiful parabola when the skater slides.

5. Gu Ailing won the championship: rotation angle

Gu Ailing staged a two-week 1620-degree off-axis rotation when she fell behind her opponent in the first two jumps. The number of turns directly reflects the difficulty of ski jumping, from 1080, 1440 degrees to 1620 degrees, the difficulty is super doubled, and it miraculously wins the championship.
