高中阶段数学所有公式汇总
一、对数运算
$\log_a(MN) = \log_a M + \log_a N$
$\log_a\dfrac{M}{N} = \log_a M - \log_a N$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
$\log_a M^n = n\log_a M$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
换底公式:$\log_a b = \dfrac{\log_c b}{\log_c a}$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
二、排列组合
排列:$A_n^m = n(n-1)(n-2)\cdots(n-m+1) = \dfrac{n!}{(n-m)!}$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
组合:$C_n^m = \dfrac{A_n^m}{m!} = \dfrac{n!}{m!(n-m)!}$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
$C_n^m = C_n^{n-m}$;$C_{n+1}^m = C_n^m + C_n^{m-1}$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
三、二项式定理
$(a+b)^n = \sum_{k=0}^n C_n^k a^{n-k}b^k$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
通项:$T_{k+1} = C_n^k a^{n-k}b^k$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
四、复数
$i^2 = -1$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
$z = a + bi$,模 $|z| = \sqrt{a^2+b^2}$,共轭 $\bar{z} = a - bi$文章源自公式库网-https://www.gongshiku.com/html/201908/94dc11f992.html
五、定积分
牛顿-莱布尼兹公式:$\int_a^b f(x)dx = F(b) - F(a)$
六、极坐标
$x = \rho\cos\theta$,$y = \rho\sin\theta$,$\rho^2 = x^2 + y^2$
