You should know that . So let and keep adding terms until you reach your required accuracy (i.e. stop when you have enough digits repeating).

so you get:

1 - (0.75^2/2) +(0.75^4/4!) - (0.75^6/6!).....

would the polynomial answer just be the first 3 terms (up to the 4th power)? - November 6th 2012, 03:22 PMProve ItRe: Need help with Taylor Polynomial approximation
