or \mathrm f
.
Function
- $\map f x$
The letter $f$, along with $g$ and $h$, is frequently used to denote a general mapping or function, in particular a real function.
The $\LaTeX$ code for \(\map f x\) is \map f x
.
Force
- $f$
The usual symbol used to denote the force on a body is $f$.

.
Primitive
- $\map F x$
Given a real function $f$, the primitive of $f$ is often denoted $F$:
- $\map F x = \ds \int \map f x \rd x$
The $\LaTeX$ code for \(\map F x\) is \map F x
.
Predicate
- $F a$
Frequently used to denote a general unspecified predicate in the context of predicate logic, for example:
- $F a$ represents:
- $a$ has property $F$
The $\LaTeX$ code for \(F a\) is F a
.
False
- $\F$
Symbol generally used for falsehood.
A statement has a truth value of false if and only if what it says does not match the way that things are.
The $\LaTeX$ code for \(\F\) is \F
.
