  • This calculus 2 video tutorial provides a basic introduction into series. It explains how to determine the convergence and divergence of a series. It explains the difference between a sequence and a series. This video includes examples and practice problems with geometric series, harmonic series, and the telescoping series. It also discusses the divergence test.

      Hows Calc 3 compared to Calc 2?

    • @BigCatSoftware
      @BigCatSoftware 7 หลายเดือนก่อน +1

      @@andrean40 my school is a little weird and has Calc split into 4 parts. Our 3 consists mostly of series and sequences. After Taylor series it moved to 3D graphs and functions. From here I’m not sure what’s next. But in 4 I know it focuses all on multi variable calculus. So I guess 3 will stop right before that. Hopefully this makes sense and is helpful.

    I love all your videos! I would definitely love to see more of these Calc and Calc 2 videos! I’m currently in Calc 2 and seeing how you work through different examples definitely helps me learn how to apply those thought processes to my own problems! But I definitely need more series and sequence videos! Even if they’re just working through more complicated examples so I know how to use the limit comparison test to a p series and how to know which test to use etc!

      @xinpingdonohoe3978 2 ปีที่แล้ว

      If the limit at ∞ doesn't equal 0, like here it equals 5/7, then the series is going to be around ∞×5/7, because after while an≈5/7, and there are still an infinite number of terms left.
      Only ∞×0 is not always going to diverge, which is why the limit at ∞ must be 0.

    @kabirsethi2608 2 ปีที่แล้ว +2

    Just asking,
    As per Ramanujan Summation, 1+2+3+4+.. all the way up to infinity is -1/12. Therefore on multiplying both sides we get,
    2+4+6+....=-1/6.
    So shouldn't the answer for the first series be -1/6.
    If any mistakes please correct me as I am just learning....

    • @xinpingdonohoe3978
      @xinpingdonohoe3978 2 ปีที่แล้ว

      Ramanujan Summation is a method of applying conversant results to divergent answers, like an integral having a Cauchy Principle Value. The actual thing diverges, but -1/12 is what arises if you do the series in other branches of mathematics.
      In regular maths though, it diverges.

    • @BomBom-lo1pq
      @BomBom-lo1pq 3 ปีที่แล้ว +4

      These are the steps you have to follow when trying to find the limit of a function as the variable approaches infinity.
      You divide both the numerator and denominator by the highest power of the variable found in the denominator.
      For example, if you’re trying to find the limit when x approaches zero for:
      2x^3 +5/6x
      You will divide both the numerator and denominator by x (or multiply both by 1/x)

    • @vincentmanning1338
      @vincentmanning1338 3 ปีที่แล้ว +2

      This is okay here but in general it is probably better to use L’Hopital’s rule when dealing with limits of indeterminate form such as 0/0 or inf/inf. Simply take the derivative of the numerator and the derivative of the denominator and compute the limit as n approaches inf of the new function. Repeat as necessary
