KAJIAN APROKSIMASI PADÉ UNTUK MENGHAMPIRI SUATU FUNGSI

Most of methodes of numeric degraded to be based on almost function to in the form of polynomial. One of the formula of polynomial to become a algorithm to yield a approximation to a function are Taylor series. To a function not good enough approximation by polynomial, but good approximation by rational function. Approximation by rational function on the promise that and fulfill equation of , and named by Pade approximation. Steps to get rational function of with Pade approximation that is: taking example , later then use equation of to obtain get system equation of coefficient, afterwards look for the solving of from system equation of coefficient, here in after isn't it obtained solution to assumption early . Under consideration Pade approximation that is to draw near function of eksponensial and cosine function. To develop knowledge, Pade approxim
