List of Mathematical Abbreviations

Algebraic Abbreviations

i: imaginary unit - a complex number that is defined as the square root of -1.
j: imaginary unit - an alternative notation for the imaginary unit, often used in electrical engineering and signal processing.
ℝ: set of real numbers - a set of numbers that includes all rational and irrational numbers.
ℂ: set of complex numbers - a set of numbers that includes all real and imaginary numbers.
ℕ: set of natural numbers - a set of positive integers, including 1, 2, 3, and so on.
ℤ: set of integers - a set of whole numbers, including positive, negative, and zero.

Geometry and Trigonometry Abbreviations

sin: sine - a trigonometric function that represents the ratio of the length of the side opposite an angle to the length of the hypotenuse.
cos: cosine - a trigonometric function that represents the ratio of the length of the side adjacent to an angle to the length of the hypotenuse.
tan: tangent - a trigonometric function that represents the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle.
csc: cosecant - a trigonometric function that represents the reciprocal of the sine function.
sec: secant - a trigonometric function that represents the reciprocal of the cosine function.
cot: cotangent - a trigonometric function that represents the reciprocal of the tangent function.

Calculus Abbreviations

∫: integral sign - a symbol used to represent the definite integral of a function.
∂: partial derivative - a symbol used to represent the partial derivative of a function with respect to one or more variables.
∇: nabla symbol - a symbol used to represent the gradient of a function.
∂/∂x: partial derivative with respect to x - a symbol used to represent the partial derivative of a function with respect to the variable x.
∂/∂y: partial derivative with respect to y - a symbol used to represent the partial derivative of a function with respect to the variable y.

Statistics and Probability Abbreviations

E: expected value - a measure of the central tendency of a random variable.
Var: variance - a measure of the spread or dispersion of a random variable.
σ: standard deviation - a measure of the spread or dispersion of a random variable.
P: probability - a measure of the likelihood of an event occurring.
P(X): probability of event X - a measure of the likelihood of event X occurring.
