If a series of
positive terms is rearranged (put into a different order) then the original
series and the rearranged series either both converge (and to the same sum) or
they both diverge [45-47]

If a series
converges, then the individual terms of the series have limit zero. [sorry, I
can't find this]

**If the power
series a**_{0}** + a**_{1}**x
+ a**_{2}**x**^{2}**
+ a**_{3}**x**^{3}**
+ … has a nonzero radius of convergence
R and f(x) is the function with domain all x such
that | x | < R, f(x) being defined as the sum of the power series for x
in that domain, then**

** (1) f(x) is continuous (at every x in its
domain)**

** (2) f(x) has a derivative f'(x), which is the sum of the power
series a**_{1}** + 2a**_{2}**x
+ 3a**_{3}**x**^{2}**
+**

** (3) f(x) has an indefinite integral which
is given as the sum of the power series
c + a**_{0}**x + (a**_{1}**/2)x**^{2}**
+ (a**_{2}**/3)x**^{3}**
+ (a**_{3}**/4)x**^{4}**
+ …**

** (4) The radius of convergence for the power
series in (2) and (3) is the same as that of the original power series. [91-93,
113, 115, 116]**

**A Taylor series
converges to the original function for a
given value of x if and only if the remainder term for that value of
value of x has limit 0 as n goes to
infinity. [107, 109.0-112, 137]**
