Sorry, due to the huge number of mathematical formulas, it is impossible to list all high school mathematical formulas in 500 words. The following are some commonly used formulas in high school mathematics:

1. linear function: y=ax+b

2. Quadratic function: y=ax? +bx+c

Trigonometric functions: sinθ, cosθ, tanθ, cotθ, secθ, csθ.

4. Plane geometry: Pythagorean theorem A? +b？ =c？ Sine theorem a/sinA=b/sinB=c/sinC, cosine theorem a? =b？ +c？ -200 BC

5. Solid geometry: surface area of sphere S=4πr? , sphere volume V=(4/3)πr? , cubic surface area S=6a? , cube volume V=a? , cylinder surface area S=2πrh+2πr? , cylinder volume V=πr? h

6. Probability statistics: full probability formula p (a) = p (a | b1) p (b1)+p (a | b2) p (b2)+...+p (a | bn) p (bn), Bayesian formula p (bi |.

The above are some commonly used formulas in high school mathematics, but they still can't cover all the contents. I suggest that when you are studying mathematics, you should sort out and summarize relevant formulas according to specific knowledge points in time.
