How can a point of symmetry have a slope which isn't either

0

\pm \infty

https://math.stackexchange.com/questions/448206/how-can-a-point-of-symmetry-have-a-slope-which-isnt-either-0-or-%c2%b1-infty

Okay, thanks to Daniel Fischer I now know what's the problem with the question. They should have specified that

h > 0

. With that cleared, the graph of the function would have been something like: The ...

sinc (x)

is continuous on

[0, \infty)

https://math.stackexchange.com/q/1003986

It is obvious that

s i n c

is continuous on

(0, \infty)

, since it is a composite of two continuous functions. To prove continuity of

s i n c

x = 0

, you must show that

lim_{x \to 0} s i n c (x) = s i n c (0)

Determine whether

\sum_{n = 1}^{\infty} \frac{x ^{2}}{n ^{2}}

converges uniformly on

[5, \infty)

https://math.stackexchange.com/q/599004

n

, we can find an

x \in [5, \infty)

∣ f_{n} (x) - f (x) ∣ = ∣ ∣ ∣ ∣ \sum_{k = 1}^{n} \frac{x ^{2}}{n ^{2}} - \sum_{n = 1}^{\infty} \frac{x ^{2}}{n ^{2}} ∣ ∣ ∣ ∣ > 1

How do we find such an

x

Question on wikipedia's proof of rolles theorem

https://math.stackexchange.com/q/1040566

(\frac{f ( c + h ) - f ( c )}{h} \leq 0 for all h > 0) ⟹ lim_{h \to 0^{+}} \frac{f ( c + h ) - f ( c )}{h} \leq 0

In other words, the limit of something never exceeding

0

0

. Suppose the ...

\sum_{1}^{\infty} e^{n (1 - x)} x^{n}

and it's Uniform/Pointwise Convergence on different intervals

https://math.stackexchange.com/q/1662836

For the first part, note that the series is not a power series so you can't talk about the "radius of convergence". Note that your series is a geometric series in disguise:

\sum_{n = 1}^{\infty} e^{n (1 - x)} x^{n} = \sum_{n = 1}^{\infty} (e^{1 - x} x)^{n} = \sum_{n = 1}^{\infty} y^{n}
