# Latin Alphabet

The Latin Alphabet is a collection of 26 symbols that form the basis of the English language. In mathematics, the Latin Alphabet’s symbols are used extensively to represent variables, constants, and coeffecients found in math expressions, formulas, and equations. The Greek Alphabet is also used for the same purpose.

## Lower Case Letters

Symbol Description The latin letter a is used to represent a variable or coefficient. The latin letter is used in math to represent a variable or coeffecient. The latin letter is used in mathematics to represent a variable or coeffecient. The latin letter d. The latin letter in is used in math to represent Euler’s Number. Euler’s number is a constant related to exponential growth that appears in many formulas and math equations as shorthand for the exponential function and as the base of the natural logarithm function. The latin letter f is used in mathematics to represent the name of a generic mathematical function The latin letter g is often used in mathematics to represent a function. Typically, the symbol is used in a expression like this: . In plain language, this represents the function which takes in a number as input. The latin letter h is used in math as a variable. It appears in many geometric formulas for area and volume to represent the height of a shape. The latin letter is used in mathematics to define complex numbers, where represents the square root of negative one. The symbol is also used in computing and linear algebra as an index variable. The latin letter j. The latin letter k is used in math as a variable. It commonly appears as an index variable for matrices along with the other letters i, j, and l. The latin letter l. The latin letter m. The latin letter n is commonly used in math as a variable. The latin letter o. The latin letter p. The latin letter q. The latin letter r is used in math as a variable. It appears in geometric equations as a variable to represent the radius of a circle. The latin letter s is used in statistics to represent the sample standard deviation. The latin letter t. In mathematics the symbol 't' is often used in equations as a variable to represent time. The latin letter u. The latin letter v. The latin letter w. The latin letter x is used to represent a variable or coefficient. In algebra, x is often used to represent an unkown value. The symbol x is also used to represent the horizontal dimension in the 2D cartesian coordinate system. The latin letter y is used to represent a variable or coefficient. Most commonly, y is the vertical dimension in the 2D cartesian coordinate system. The latin letter z is used to represent a variable or coefficient. The symbol z is also used to represent the up/down dimension in the 3D cartesian coordinate system.

## Upper Case Letters

Symbol Description The capital Latin letter A is used in math as a variable. In linear algebra it is commonly used to represent a matrix. It also appears in the compound interest formula as the accumulated value. The capital Latin letter B is used in probability as a random variable. The capital Latin 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 displayed using a “double-struck” typeface. The capital Latin letter D is used in mathematics as a variable. The capital Latin letter E. The capital Latin letter is used in mathematics to represent the anti-derivative of a function . The capital Latin letter G. The capital Latin letter H. The capital Latin letter I is used in math to represent the identity matrix sometimes with subtext to represent the size of the matrix. The capital Latin letter J. The capital Greek letter (Kappa) is visually very similar to the upper-case Latin letter K. For that reason, refer to the usage of Capital K for how the symbol appears in math. The capital Latin letter L. The capital Latin letter M. The capital Latin letter N is used in mathematics to represent the set of natural numbers. Usually, the letter is presented with a “double-struck” typeface to indicate that it is the set of natural numbers. Otherwise, N is also used as a variable. The capital Latin letter O. The capital Latin letter is used throughout mathematics as a variable. The symbol is used to represent a point in space in the cartesian coordinate system. The symbol is used in various formulas and in statistics the symbol is used to represent a probability distribution. The capital Latin letter Q is used in mathematics to represent the set of natural numbers. Usually, the letter is presented with a “double-struck” typeface when it is used to represent the set of rational numbers. The capital Latin letter R is used in mathematics to represent the set of real numbers. Usually, the letter is presented with a "double-struck" typeface when it is used to represent the set of real numbers. The capital Latin letter S is used in math to represent the partial sum of a series. The capital Latin letter T. The capital Latin letter U. The capital Latin letter is commonly used in math as a variable to represent volume. The capital Latin letter W. The capital Latin letter X is used to represent a random variable in statistics The capital Latin letter Y. The capital Latin letter Z is used in mathematics to represent the set of integers. Usually, the letter is presented with a "double-struck" typeface to indicate that it is the set of integers.
