Root mean square definition

WebIn mathematics, a square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number. f (x) = √x For example, if x=4, then the function returns the output value as 2. Note: The square root of a negative number represents a complex number. WebRoot-Mean-Square. Definition: The effective value of alternating current or voltage.
