Question

How do you solve a maclaurin series when the value of all the derivatives at 0 will always be 0? e.g. x^2*sin(x/3)

Answer 1

nvm figured it out :)

Answer 2

can you explain it to me? xD
i didn't :P

Answer 3

Well, you basically find the maclaurin series for sin(x/3) then multiply by x^2. Check out this video: http://www.youtube.com/watch?v=3ZOS69YTxQ8 It's about using the maclaurin series to estimate a definite integral, but the first part shows how to find the maclaurin series of a very similar function. That's how I figured it out. :)

thx i'll have a look
