1 Closure categorization. 2  Check and confirm that the initial incident categorization was correct or, where the categorization subsequently turned out to be incorrect, update the record so that a correct closure categorization is recorded for the incident-seeking advise or guidance from the resolving group(s) as necessary.
In mathematics, the term generating function is used to describe an infinite sequence of numbers (a n) by treating them as the coefficients of a series expansion. The sum of this infinite series is the generating function.
Like the sine and cosine functions, the inverse trigonometric functions can be calculated using power series, as follows. For arcsine, the series can be derived by expanding its derivative, , as a binomial series, and integrating term by term (using the integral definition as above).
