点击CSDN写博客的编辑界面工具栏中的Σ按钮，就可以插入LaTeX代码了。

左为效果，右为代码，中间用四个空格分隔

**四则运算**

![\+][gif.latex_plus]    +

![\-][-]    -

![\\times][times]    \\times

![\\div][div]    \\div

小练习：

![(2\\times5+6)\\div3-1][2_times5_6_div3-1]    (2\\times5+6)\\div3-1

**分式**

![\\frac\{A\}\{B\}][frac_A_B]    \\frac\{A\}\{B\}

**乘方与幂函数**

![x^\{a\}][x_a]    x^\{a\}

**开方**

![\\sqrt5][sqrt5]    \\sqrt5

![\\sqrt\[3\]5][sqrt_3_5]    \\sqrt\[3\]5

**对数函数**

![\\log\_23][log_23]    \\log\_23

![\\log\_\{19\}\{35\}][log_19_35]    \\log\_\{19\}\{35\}

![\\ln 3][ln 3]    \\ln 3

![\\lg 3][lg 3]    \\lg 3

**积分、求和与连乘**

![\\int\_\{a\}^\{b\}][int_a_b]    \\int\_\{a\}^\{b\}

![\\int\_\{0\}^\{\\frac\{\\pi\}\{2\}\}][int_0_frac_pi_2]    \\int\_\{0\}^\{\\frac\{\\pi\}\{2\}\}

![\\sum\_\{i=1\}^\{n\}][sum_i_1_n]    \\sum\_\{i=1\}^\{n\}

![\\prod\_\{i=1\}^n][prod_i_1_n]    \\prod\_\{i=1\}^n

**向量**

![\\vec a][vec a]    \\vec a

![\\overrightarrow\{AB\}][overrightarrow_AB]    \\overrightarrow\{AB\}

![\\overleftarrow\{BA\}][overleftarrow_BA]    \\overleftarrow\{BA\}

**逻辑推断**

![A \\longrightarrow B][A _longrightarrow B]    A \\longrightarrow B

**上下标**

![C^2\_3][C_2_3]    C^2\_3

**常用字母**

![\\alpha][alpha]    \\alpha

![\\beta][beta]    \\beta

![\\gamma][gamma]    \\gamma

![\\pi][pi]    \\pi
