Homework Help: Help with Taylor Series

  1. Dec 2, 2009 #1
    1. The problem statement, all variables and given/known data

    What function produces the following:
    ([tex]\pi[/tex]2/(22)) - ([tex]\pi[/tex]4/(24*3!)) + ([tex]\pi[/tex]6/(26*5!)) - ([tex]\pi[/tex]8/(28*7!))

    I'm sure this is a sin function.
    But I can't figure out what exactly is the function.

    Please help.

    That can be written as

    [tex] \pi/2[\pi/2 - (\pi/2)^3/3! + (\pi/2)^5/5! + ...] [/tex]

    Is that my final answer?
    Or would sin(pi/2) be it?
