The order corresponds to the number of terms in a Taylor series. <br /><br />And, just as Taylor series have a limited range of applicability (not all functions can be Taylor expanded), so has this perturbative expansion.Axel Maashttp://www.blogger.com/profile/16708869827696572827noreply@blogger.comtag:blogger.com,1999:blog-3289825502161718378.post-66752024606597082982012-01-31T05:40:44.739-08:002012-01-31T05:40:44.739-08:00How similar is this to doing a Taylor series expan...How similar is this to doing a Taylor series expansion to approximate (say) Sin theta or exponential of x? If so are the different "orders" equivalent to including in extra terms in the series? - @doubledodgeAnonymousnoreply@blogger.com
