pt) Determine if the following sequences converge or diverge, if the sequence
converges, then find the limit:
a) b)
c) where
2.
(12
pt) Consider the sequence where is the nth
partial sum of the series
a)
Find
all values of p for which the
sequence converges (and state why).
b)
Find
all values of p for which the
sequence does not converge to 0 (and state why).
3.
(36
pt) Determine if the following series converge or diverge:
a) b) c)
d) e) f)
4.
(12
pt) For this problem consider the two convergent series
a)
How
big must you choose n to guarantee that the approximation sn
for the series has error less than or equal to .01?
b)
How
big must you choose n to guarantee that the approximation sn
for the series has error less than or equal to .01?
5.
(10
pt) Find the center, radius, and interval of convergence of the power series
6.
(9
pt) Suppose that if you expand the function in a power series
about c, is equal to its power series on the interval (0,c).
Also assume that has a vertical asymptote at 0. Suppose you expand in a Taylor series centered at 1. Determine if you can use
this series to estimate the following in general: Why or why not?
7.
(8
pt) Evaluate the integral with error less than .001.
8. (8 pt) Find a series for about What is the radius of convergence of this series?
