The \boxdot
is a Tex command that outputs a boxed dot symbol, which can be used for various purposes in mathematical formulations. The command is part of the amssymb
package, so it must be included in the preamble of a document before it can be used.
The syntax for the \boxdot
command is as follows:
\boxdot
Here is an example of how the \boxdot
command can be used in a mathematical expression:
Let X be a set with n elements, and let Y be a set with m elements. Then the number of one-to-one mappings from X to Y is given by \frac{m!}{(m-n)!}\boxdot
The output of this command is as follows:
Let X be a set with n elements, and let Y be a set with m elements. Then the number of one-to-one mappings from X to Y is given by $\frac{m!}{(m-n)!}\boxdot$
In conclusion, the \boxdot
Tex command is a useful tool for mathematical expressions that require a boxed dot symbol. It is easy to use and can be included in any Tex document by including the amssymb
package in the preamble.
