Introduction to \cup-TeX commands

\cup-TeX is a set of TeX commands that allow programmers to typeset mathematical symbols and expressions. These commands are similar to LaTeX commands but have some differences in syntax and functionality.

Basic \cup-TeX commands

The following commands are some of the basic \cup-TeX commands that can be used to typeset mathematical expressions:

• \cup: This command is used to typeset the union symbol. For example, $A \cup B$ renders as $A \cup B$.

• \cap: This command is used to typeset the intersection symbol. For example, $A \cap B$ renders as $A \cap B$.

• \times: This command is used to typeset the multiplication symbol. For example, $a \times b$ renders as $a \times b$.

• \div: This command is used to typeset the division symbol. For example, $a \div b$ renders as $a \div b$.

• \sqrt: This command is used to typeset the square root symbol. For example, $\sqrt{x}$ renders as $\sqrt{x}$.

Advanced \cup-TeX commands

The following commands are some of the advanced \cup-TeX commands that can be used to typeset more complex mathematical expressions:

• \frac: This command is used to typeset a fraction. For example, $\frac{a}{b}$ renders as $\frac{a}{b}$.

• \int: This command is used to typeset an integral symbol. For example, $\int_{x=0}^{x=1} f(x) dx$ renders as $\int_{x=0}^{x=1} f(x) dx$.

• \sum: This command is used to typeset a summation symbol. For example, $\sum_{i=1}^{n} x_i$ renders as $\sum_{i=1}^{n} x_i$.

• \prod: This command is used to typeset a product symbol. For example, $\prod_{i=1}^{n} x_i$ renders as $\prod_{i=1}^{n} x_i$.

• \lim: This command is used to typeset a limit symbol. For example, $\lim_{x\to\infty} f(x)$ renders as $\lim_{x\to\infty} f(x)$.

Conclusion

In conclusion, \cup-TeX commands provide a powerful and flexible way to typeset mathematical expressions in TeX. By using these commands, programmers can easily create complex mathematical expressions that are both clear and easy to read.
