In statistics, Bochner's theorem can be used to describe the serial correlation of certain type of time series. A sequence of random variables of mean 0 is a (wide-sense) stationary time series if the covariance only depends on n − m. The function is called the autocovariance function of the time series. By the mean zero assumption, WebSperner's theorem, in discrete mathematics, describes the largest possible families of finite sets none of which contain any other sets in the family.

WebHeron’s formula is a formula to calculate the area of triangles, given the three sides of the triangle. This formula is also used to find the area of the quadrilateral, by dividing the quadrilateral into two triangles, along its diagonal. If a, b and c are the three sides of a triangle, respectively, then Heron’s formula is given by:
