Hello Over what range may I calculate definite integrals via these series'. For instance, a Maclaurin series is 'centred' around x = 0 and the function will have its best 'fit' at x = 0; surely this will make integrals over a wide range of x (say between 0 and 1000) inaccurate? I cannot seem to find any information on this. Hope it makes sense! Thanks

It very much depends on the nature of the the function. In any case, it will be a question of how fast the integrated series converges.
