I have hard time understanding "Such That"
{x\inZ|x=2m+1, m\inZ}
Is this saying that x is apart of all integers and because of that x=2m+1 where m is all so apart of all integers.
if not
Is the first part x\inZ because of the second part x=2m+1, m\inZ
or
Is second part...
So I know how to find the "Interval of Convergence" for a power series representation of a Function f(x).
But I Still don't know what that "Interval of Convergence" does for me other than I can choose a number in it and plug it into the series.
For Example[SIZE="4"] e^{x}=\sum^{∞}_{n=0}...
When I say a series \suma_{n} converges, what exactly is it that I am saying?
for example
\sum^{∞}_{n=1}\frac{9n^{2}}{3n^{5}+5} is convergent. what did I just say?
so recently I have learned how to convert a function f(x) into a Power series, but I am still lost as to why I did that in first place? Explain this please.
I read the definition of discrete math and i read the definition of discrete.
i just can't seem to figure out what discrete math is, can you guys show what it means?
