The latin letter is used in mathematics to represent a variable or coefficient.
The Latin capital letter C is used in mathematics as a variable. For example, it appears in geometric formulas as a variable representing the circumference of a circle. It also is used to represent the set of complex numbers, although this is usually indicated with a "double-struck" typeface.
A variable is a core concept in algebra where a symbol, usualy a lower case latin letter, is used as a placeholder in a math expression.
