statistics - What are differences between Geometric, Logarithmic …
2020年8月3日 · 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, 2•2•2•2•2=32. The conflicts have made me more confused about the concept of a dfference between Geometric and exponential growth.
terminology - Is it more accurate to use the term Geometric …
I'm probably wrong, but I think if people differentiate between the two: "geometric" implies rapid growth/decay but with a constant rate while "exponential" implies rapid growth/decay with an accelerating rate. I believe a lot of non-mathy people use "exponential" because it sounds impressive, more impressive than "geometric".

Calculate expectation of a geometric random variable
2013年12月13日 · 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, an extremely enjoyable course) and based on (a) the memoryless property of the geometric r.v. and (b) the total expectation theorem.
Geometric series of complex numbers - Mathematics Stack Exchange
2021年3月14日 · Let $ z $ be a complex number. I want to find the radius of convergence of $$ \sum_{n=0}^{\infty}z^{n} $$. My intuition is that this series converges for $ z\in D\left(0,1\right) $ (open unit disk).
Geometric meaning of the determinant of a matrix
2016年2月10日 · What is the geometric meaning of the determinant of a matrix? I know that "The determinant of a matrix represents the area of a rectangle." Perhaps this phrase is imprecise, but I would like to know something more, please. Thank you very much.

When is a Power Series a Geometric Series? - Mathematics Stack …
$\begingroup$ 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 example $\sum x^n$ is geometric, but …
What does the dot product of two vectors represent?
2014年5月23日 · It might help to think of multiplication of real numbers in a more geometric fashion. $2$ times $3$ is the length of the interval you get starting with an interval of length $3$ and then stretching the line by a factor of $2$. For dot product, in addition to this stretching idea, you need another geometric idea, namely projection.
