1. (4p.) Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues:

1. (12p.) Determine whether the sequence converges or diverges. If it converges, find the limit. MATH序列代考

1. (12p.) Determine whether the series is convergent or divergent. If it is convergent, find its sum.

1. (10p.) Use the binomial series to expand the function as a power series. State the radius of convergence: (1+ x)3/4 .
1. ### (32p.) Test the series for convergence or divergence. MATH序列代考

1. (8p.) Use any test to determine whether the series is absolutely convergent, conditionally convergent, or divergent.

1. ### (8p.) Find the radius of convergence and interval of convergence of the series: MATH序列代考

1. (10p.) Express the function as the sum of a power series by first using partial fractions. Find the radius of convergence. f(x) =(2x – 4)/(x2 – 4x + 3).
1. (8p.) Show that 0.9999…= 1
2. (10p.) Find the Maclaurin series for f (x) using the definition of a Maclaurin series. Also find the associated radius of convergence: f(x) = 10x
1. (12p.) Find the Taylor series for f (x) centered at a = π/6 using the definition of a Taylor series ???? ???? ?ℎ? ?????????? ?????? ?? ???????????: ?(?) = ????.
1. ### (8p.) Use series to evaluate the limit. MATH序列代考

1. (8p.) Find the sum of the series.
1. (8p.) Evaluate the indefinite integral as a power series. What is the radius of convergence?
