## Introduction
A moon orbiting a planet, a dog running along a beach, a river spilling over the side of a cliff—all of these are examples of objects in motion. When we say something is in motion, we generally mean simply that it is moving. In science, however, motion is defined as the change of the position of an obj... | HuggingFaceTB/finemath | |

Add 3/35 and 10/30
3/35 + 10/30 is 44/105.
Steps for adding fractions
1. Find the least common denominator or LCM of the two denominators:
LCM of 35 and 30 is 210
2. For the 1st fraction, since 35 × 6 = 210,
3/35 = 3 × 6/35 × 6 = 18/210
3. Likewise, for the 2nd fraction, since 3... | HuggingFaceTB/finemath | |

Explain the Hamming Codes in Error Correction
The Hamming code can be used to the data units of any length when we consider the two codewords which have the same length. The Hamming distance between two codewords is represented as the number of positions in which their specific item differs.

Density-Dependent Population Growth Simulation
Recall Equation 42.4 for multiplicative population growth:

If the time ΔT between breeding episodes in the population becomes vanishingly small (as in human populations—births occur throughout the year rather than seasonally), this can be written as a diff... | HuggingFaceTB/finemath | |
Complex number inequality?
Suppose $|z|>1$ for $z$ a complex number. I'm trying to build a certain comparison test to test convergence. I'm wondering, is it true that $$\frac{1}{|1+z^n|}\leq\frac{1}{|z|^n-1}?$$
-
Yes. By triangle inequality, we have $$|z|^n=|z^n|=|z^n+1-1|\leq|z^n+1|+1.$$ This implies that $$|z|^n-1... | HuggingFaceTB/finemath | |

A while ago in this post, I proved that the sum of divisors of an integer can be computed as a multiplicative function on primes.

When dealing with statistics there are times when data get skewed by having a high concentration at the one end and lower values at the other end. These results in a peak towards one end that trails off. One way of dealing with this type of data is to use a logarithmic scale to give it a more normal pattern to the data... | HuggingFaceTB/finemath | |
