    Limits Observation

    Let {a_{n}} be a sequence. \lim_{n\rightarrow \infty}a_{n}=L if, given \epsilon, N exists st |a_{n}-L| < \epsilon for all n > N but there are an infinite number of sequences which satisfy this condition, NO MATTER WHAT \epsilon is, namely all sequences which are the same up to a_{N}, so...

    Can you help me to demonstrate these limits? [It's URGENT!!!!]

    Hello! :wavespin: Thank you for bothering to help me with this.... I need you to please help me with these points of my calculus activity. ;) The subject is called Trigonometric Limits. The first one [A] has to be demonstrated using the sandwich theorem. And the second [F] has to be...

    Limits to topology?

    What effect has replacing the spaces of each genus-one manifold with a genus-zero solid, and vice versa? Is a singularity -- solid or spatial -- allowed in topology? Can a topology invert universally from a solid or spatial singularity to approach infinity (while conserving their manifold...

    Closed Thread: Real Numbers and Limits.

    Why was subject thread only closed after I attempted to respond to a question? What I have to say was not said before, that an infinite decimal sequence, THE SEQUENCE, is the real number, not it's calculus limit. If someone was interested in what I had to say, why couldn't I respond without...

    Real Numbers and Limits

    REAL NUMBERs are defined uniquely by "infinite" (unending) sequences of natural numbers. The sequence IS the real number. LIMIT is a defined property of real numbers.

    Limits' and reals' cardinality

    Does the limit function relate to a maximum cardinality? Does the set of real numbers, as they are an "absolute" continuum? Can one map the set of real numbers onto a finite surface? By bijection?

    help with limits of sequences

    Hello I really troubled with the following questions u_n = \left(\frac{2n^3 - 4n^2 + 5}{10n^3 + 100}\right)\cdot2^{-n} w_n = \left(\frac{3n + 2}{4n^2 + 8n + 5}\right)\cdot\left(\frac{(1 - n)^3}{(14 - 5n)^2}\right) e_n = \frac{2^n + 3^{n - 1} + 5^{2n + 2}}{4^{n - 7} + 5^{2n}} b_n =...

    Demonstration that the derivative of ln equals 1/x

    Hi! Nice to meet you all <333 I would be tremendously grateful if you could possibly give an answer to my questions and help me with this. I have two questions: first of all, what is the limit of an exponential function as x approaches 0? Is it 1? Second one: how exactly could I...

    String twist limits

    Take a string initially of diameter D and length L, where L>>D. Twist the string until it forms a helix. Repeat until the limit near L~D. What is the resultant geometry? Take a string with the above starting L and D, connecting ends with itself to form a "torus" with N/2 string twists, where...

    Statements True Or False (Limits)

    This is the question i can't solve. I graphed the functions here. But finding the statements is somehow not clear for me for example i don't know what will be the limit on x=2.
