In multivariable calculus, the partial derivative of a function is the derivative of one variable when all other variables are held constant. In other words, a partial derivative takes the derivative of certain variables of a function while not differentiating other variable(s). Partial derivatives are often used in multivariable functions.
For partial derivatives of function f with respect to variable x, the notation

is standard,[1][2][3] but other notations are sometimes used.
