  1. When is a Power Series a Geometric Series?

    So surely you see the answer now, but I'll state it for the record: a power series is a geometric series if its coefficients are constant (i.e. all the same). In particular, not all power series are geometric. For …

  2. why geometric multiplicity is bounded by algebraic multiplicity?

    The geometric multiplicity is the number of linearly independent vectors, and each vector is the solution to one algebraic eigenvector equation, so there must be at least as much algebraic multiplicity.

  3. statistics - What are differences between Geometric, Logarithmic and ...

    Aug 3, 2020 · Now lets do it using the geometric method that is repeated multiplication, in this case we start with x goes from 0 to 5 and our sequence goes like this: 1, 2, 2•2=4, 2•2•2=8, 2•2•2•2=16, …

  5. Expectation of the square of a geometric random variable

    Apr 12, 2017 · There are two closely related versions of the geometric. In one of them, we count the number of trials until the first success. So the possible values are $1,2,3,\dots$. In the other version, …

  6. Calculate expectation of a geometric random variable

    Dec 13, 2013 · 2 A clever solution to find the expected value of a geometric r.v. is those employed in this video lecture of the MITx course "Introduction to Probability: Part 1 - The Fundamentals" (by the way, …

  7. terminology - Is it more accurate to use the term Geometric Growth or ...

    For example, there is a Geometric Progression but no Exponential Progression article on Wikipedia, so perhaps the term Geometric is a bit more accurate, mathematically speaking? Why are there two …

  8. What is the difference between arithmetic and geometrical series?

    Nov 26, 2014 · 4 Geometric and arithmetic are two names that are given to different sequences that follow a rather strict pattern for how one term follows from the one before. An arithmetic sequence is …

  9. Arithmetic or Geometric sequence? - Mathematics Stack Exchange

    Nov 1, 2016 · A geometric sequence is one that has a common ratio between its elements. For example, the ratio between the first and the second term in the harmonic sequence is $\frac {\frac {1} {2}} …

  10. How to Recognize a Geometric Series - Mathematics Stack Exchange

    Apr 1, 2016 · The definition of a geometric series is a series where the ratio of consecutive terms is constant. It doesn't matter how it's indexed or what the first term is or whether you have a constant.
