1、常用的数学符号和公式的读法,1 逻辑(Logic)for allp q if p,then qpqp if and only if q,数学公式的读法(Pronunciation of mathematical expressions),2 集合(Sets)xA x belongs to AxA x does not belong to A AB A is a subset of BABB is a subset of A ABA cap BABA cup B,3 实数(Real numbers)xyx is greater than yxyx is greater than or equal
2、 to yx yx is less than yxyx is less than or equal to y0 x1zero is less than x is less than 10 x1 zero is less than or equal to x is less than or equal to 1|x|mod x/modulus xx2x squared/x(raised)to the power 2x3x cubed;the third power of xx4 x to the fourth/x to the power fourxn x to the nth/x to the
3、 power nx-n x to the(power)minus n,3 实数(Real numbers)n!n factorial(x+y)2 x plus y all squared the sum from i equals one to n aix over y all squared,4 函数(Functions)f(x)fx/f of x/the function f of x f:STa function f from S to Tx maps to yf(x)f prime xf(x)f doubleprime xf(x)f tripleprime xf(x)the fourt
4、h derivative of f with respect to x,常量:constant变量：variable极限：limit无穷大：infinity无穷小：infinitesimal极大：maximum极小：minimum微分：differential积分：integral导数：derivative特解：particular/special solution通解：general solution全解：complete solution,矩阵：matrix行矩阵：row matrix列矩阵：column matrix单位阵：unit matrix对角阵：diagonal matrix逆矩阵：inverse matrix转置矩阵：transposed matrix向量：vector标量：scalar概率：probability随机变量：random variable均值：mean方差：variance,
