Hi, good morning!
I'm having trouble with vector space.
Let there be α and β some given numbers. Prove that the set of all the real numbers f(x) so that: α*f(-2) + β*f(5) = 0 is a vector space !
Could someone please write a full solution for he axiom scalar multiplication?
hi :)
Quick questions:
How can I write a series converging into the limit of pai ?
Prove that the limit of the series zz (n+2) / (2n² +1) zz is not 1/2 when n->infinity (and bigger than 1)
I came to the equation:
zz |(-2n² + 2n +3) / (2n² +1) | >= ε zz
(*)And I made the left...
the limit exists if for each ε > 0 there exists an R such that qqq |f(x) - L| < ε whenever x > R
so the limit does not exists when |f(x) - L| < ε whenever x < R ?
hi :]
a couple of questions:
1) Using epsilon and N, write in a formal manner the following statement:
L is not a the limit of the general series {an} when n goes from 1 to infinity.
2) prove the next sentence: if a series an is converging into a final limit L, then the arithmetic...
Good morning :)
I got a couple of question, hope I won't bother you guys too much.. its about function limits.
1)

what I tried to do was to say that for all delta>x-(7/4) there is 3x/(4x-7)>M
than I tried...

Good morning from Israel :smile:
I'm a first year student learning about function limits.. I need to prove / disprove the following statements which I got a bit tangled up with..
" Prove or disprove...
I had to prove the equation, but I figured it out.
Same for 2, I need to prove the equation and not just asume that it exists!
That one I couldn't prove..

I need to prove that the left part is equal to the right. I'm not sure how to approach the question.
I know that (n over k)=n! : k!(n-k)! but how do I sum all the number from k=0...
