这个环境需要一个参数,即“等号列”的数量,在所有行中取&s数量的最大值,再加1除2。(A variant environment alignat allows the horizontal space between equations to be explicitly specified. This environment takes one argument, the number of “equation columns": count the maximum number of &s in any...

In some multiple integrals (i.e., integrals containing more than one integral sign) one finds that LaTeX puts too much space between the integral signs. The way to improve the appearance of of the integral is to use the control sequence \! to remove a thin strip of unwanted space. Thus...

In equation (1), there is hardly any space between the number and the unit. LaTeX has thought that you want to multiply 500 times “MHz” and thus it removes all spaces you write here. To force a visible space, use command \,. ...
in displayed equations we type\lim_{x \to +\infty}, \inf_{x > s}and\sup_Krespectively. Thus to obtain (in LaTeX) we type \[ \lim_{x \to 0} \frac{3x^2 +7x^3}{x^2 +5x^4} = 3.\] Added by Goldman2000@126:--- To compulsively display "u \to \...
