29-30 The limit of an indeterminate form as x -> Xo can some- times be found by expanding the functions involved in Taylor series about x = Xo and taking the limit of the series term by term. Use this method to find the limits in these exercises. sin x tan 1 29. (a) lim X - X (b) lim *=0 X x-0 7-3 1 - cos x In 30. (a) lim VI + x - sin 2x (b) lim sin x X-0
