Theorem 2: Series of Sums is equal to Sum of Series
Theorem 2: Series of Sums is equal to Sum of Series
In this video, I go over Theorem 2, which states that we can move a constant out of the sum of a series as well as add or subtract series individually. These follow from the Limit Laws of Sequences, and

Theorem 1 and the Test for the Divergence of Infinite Series
Theorem 1 and the Test for the Divergence of Infinite Series
In this video, I go over Theorem 1, which states that the terms of a convergent series approach zero. Conversely, if the terms don't approach zero, the series diverges, hence providing a useful test for

Telescoping Sum: All the terms of this series cancel out except for the first and last term
Telescoping Sum: All the terms of this series cancel out except for the first and last term
In this video, I go over an infinite series in which arises an example of the famous telescoping sum such that all the terms of the series cancel except for the first and last term. The telescoping sum

Geometric Series: Sum of x^n series = 1/(1 - x) if |x| is less than 1
Geometric Series: Sum of x^n series = 1/(1 - x) if |x| is less than 1
In this video, I show that the infinite series xn = x0 + x1 + x2 + ... is just a geometric series, and converges if the absolute value of x is less than 1. By common convention, x0 = 1, so the first term

Converting the number 2.3171717... into the fraction 1147/495 via the Geometric Series
In this video, I go over an example of converting the number 2.3171717... (with infinite repeating 17) into a fraction by writing the repeating 17s as an infinite geometric series with common ratio 1/100,

Geometric Series: Deriving the Sum using an Ingenious Method (and via Similar Triangles)
Geometric Series: Deriving the Sum using an Ingenious Method (and via Similar Triangles)
In this video, I go over the geometric series, which is the sum a + a r + a r^2 + ..., and show that if the absolute value of the common ratio r is less than 1, then the sum is just the first term divided

Vortex Math Doubling Patterns: 1248751, 3636, 9999
Vortex Math Doubling Patterns: 1248751, 3636, 9999
In this video I show the patterns that arise when we continuously double and take the vortex sum of numbers in the base 10 system. When doubling from 1, we get the 1248751 pattern; doubling from 3 yields

Modulo Operation – Vortex Digit Sum is Equal to the Mod (base - 1)
Modulo Operation – Vortex Digit Sum is Equal to the Mod (base - 1)
In this video I go over the modulo operation which returns the remainder of a division between two numbers. For example 100 mod 9 = 1 because 100/9 = 99 + 1/9, hence 1 is the remainder. I then prove that
