  • Does the sequence converge? Is it also Cauchy?

    Let a_1=1 and let a_(k+1)=1/(a_k)

    Determine whether a_k converges or diverges. Also, if it converges, is it Cauchy?

    Note: "a_k" means "a subscript k"

  • Ex Gf still wants to be with me but I just don't feel the same way?

    My ex and I have been apart for about 2 months. Today she texts me and asks if I wanna hang, I reply "I have other plans. I have to go umpire a little league game." Which is true, but then she texts me back saying, "You want to date again?" I haven't replied since then, I'm not that into her anymore. Is there a way to let her down easy without hurting her too much??

    Thank you in Advance

  • Using li(x) to approximate the number of prime numbers.?

    Use the "logarithmic integral function, or li(x)" to approximate the number of primes less than 10^6.

    I know that li(x)=integral(dt/ln(t)), t=0 to t=x, but I don't know how to use it to approximate the number of primes.

  • Uniform Continuity and Induction?

    Let f: R-->R be defined by f(x)=x^k, for any natural number k. Determine what values of k, if any, make f uniformly continuous over R. If there does not exist such k, use induction to verify it.

  • Guinea Pig makes various sounds, what do they mean?

    My guinea pig makes various squealing sounds and similiar sounds. I know some of the sounds mean that he feels threatened because the cat is near his cage. But he still makes them even when there are no potential threats around. I'm just wondering what all the different sounds mean?

  • Why would she say this? Plz help girls?

    Now I met this girl Thursday, we talked for a while and hit it off and she gave me her number. I text her later that night, "Hi" and we get to know each other, nothing big just our interests. She then texts me "I think your the sweetest guy I've talked to. Ever." How? Why would she say this when she hardly even knows me?

  • Gamma Function Basic Properties?

    Determine the domain of the Gamma function. Also, show that Gamma(n-1)=n!. We are studying the Gamma function in Real Analysis and I'm completely lost.

    Note: I used the notation Gamma(n) to denote the Gamma function's value at n. And n is any positive integer.
