[DTube] Geometric Series: Deriving the Summation FormulassteemCreated with Sketch.

in #dtube • 6 years ago (edited)

I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain

In this video, we derive the formulas for summing a geometric series, firstly to the nth term and then to infinity.

The formulas are:

  1. Sn = a(rn - 1) / r - 1

  2. S∞ = a / r - 1

We also discuss the concept of convergence and divergence for the geometric series.

Sequences & Series

  1. What are Geometric Sequences?
  2. Modelling Price Inflation with Geometric Sequences
  3. Geometric Sequences: Find the 4th term given the 7th term
  4. Geometric Sequences: Find the first term and common ratio
  5. Geometric Sequences: The Geometric Mean
  6. Geometric Series: Deriving the Summation Formulas

Thanks for watching. Please give me a "thumbs up" if you have found this video helpful.

Please ask me a maths question by commenting below and I will try to help you in future videos.
