$\mathbf{Q}$is the set of rational numbers. So we use the\ mathbfcommand. Which give: Qis the set of rational numbers. You will have noticed that in recent books, we use a font that is based on double bars, this notation is actually derived from the writing of classic sets on the ...
$\mathbf{R}$is the set of real numbers. So we use the\ mathbfcommand. Which give: Ris the set of reals. You will have noticed that in recent books, we use a font that is based on double bars, this notation is actually derived from the writing of cl...
The set of all real numbers is denoted by $\mathbb{R}$ and is infinite, i.e., it contains an infinite number of elements: $\mathbb{R} = \{ x \mid x \in \mathbb{R} \} \sim \infty$. 在这个例子中,无穷大符号被用来强调实数集R\mathbb{R}R是无限大的。 总之,使用\infty命令是在...
