Lagrange remainder vs. Alternating Series Estimation Theorem: do they always provide the same error bound?
If a function has a nth degree Taylor series approximation, we can use the Lagrange form of the remainder to calculate the maximum value of the error of approximation. If the series is also an alternating series, we can use the Alternating Series Estimation Theorem to get another maximum value of the error of approximation. It is not guaranteed that the two maximums will always be the same.

If the Taylor Series of $\ln (x)$ is known:
$\ln (x) = (x - 1) - \frac{1}{2} (x - 1)^{2} + \frac{1}{3} (x - 1)^{3} - \frac{1}{4} (x - 1)^{4} + \frac{1}{5} (x - 1)^{5} - . . .$
Can one find the Taylor series of
$f (x) = \frac{x}{1 - x^{2}}$
by manipulating the Taylor series of $\ln (x)$ ?

Prove that if $f$ is defined for $| x | < r$ and if there exists a constant $B$ such that
$| f^{n} (x) | \leq B$
for all $| x | < r$ and $n \in N$ , then the Taylor series expansion :
$\sum_{n = 0}^{\infty} \frac{f^{(n)} (0) x^{n}}{n!}$
converges to $f (x)$ for $| x | < r$ .

Are there instances when a Taylor series and a Laurent series of the same function about the same point ever equal?

Let $F (x)$ be the unique function that satisfies $F (0) = 0$ and $F' (x) = \frac{\sin (x^{3})}{x}$ for all $x$ . Find the Taylor series for $F (x)$ about $x = 0$ .
Wouldn't the value of every derivative at $0$ just be $0$ ? So how does a Taylor series even exist?
If $F (0) = 0$ , then can the Taylor series of $F (x)$ be the same as that of $F^{'} (x)$ ?

Let $f (x)$ and $g (x)$ be two Taylor series such that:
$f (x) = \sum_{n = 0}^{\infty} (- 1)^{n} a (n) x^{n}$
and
$g (x) = \sum_{n = 0}^{\infty} b (n) x^{n}$
for $a (n) > 0$ and $b (n) > 0$ .
Can we extract the asymptotic behavior of these two taylor series for $x \to \infty$ ?

Taylor Series are an essential tool in mathematics that allow the expansion of functions into an infinite sum of terms. It is a powerful way to approximate complicated functions, or to find a formula for the nth derivative of a function. The Taylor Series formula is based on the concept of derivatives, and is made up of an infinite number of terms that represent the successive derivatives of the function at a particular point. Working with Taylor Series can be tricky, so practicing Taylor Series problems is a great way to gain a better understanding of the formula and its applications. Fortunately, we have plenty of equations and practice problems to help students learn Taylor Series. So if you are struggling with Taylor Series, don't hesitate to look for help!
