poles lie at a distance ωn from the origin, and at an angle ±cos−1(ζ) from the negative real axis The poles for an underdamped second-order system therefore lie on a semi-circle with a radius defined by ω n , at an angle defined by the value of the damping ratio ζ
If, in the same test, your results show that you have a genetic distance of 2 (35/37), instead of zero (37/0), with one or more persons, your probability of a common ancestor drops to 71 -86 in the past 8 generations and 90-97 in the past 12 generations The percentages become rather unstable as the genetic distance increases
they tell us the exact value between units, AND they also have an absolute zero–which allows for a wide range of both descriptive and inferential statistics to be applied At the risk of repeating myself, everything above about interval data applies to ratio scales + ratio scales have a clear definition of zero Good examples of ratio

2-1 Position Displacement and Distance In describing an object’s motion we should first talk about position – where is the object? A position is a vector because it has both a magnitude and a direction: it is some distance from a zero point (the point we call the origin) in a particular direction With one-dimensional motion

Euclidean Distance
We start with the most common distance measure, namely Euclidean distance. It is a distance measure that best can be explained as the length of a segment connecting two points. The formula is rather straightforward as the distance is calculated from the cartesian coordinates of the points using the Pythagorean theorem.
Cosine Similarity
Cosine similarity has often been used as a way to counteract Euclidean distance’s problem with high dimensionality. The cosine similarity is simply the cosine of the angle between two vectors. It also has the same inner product of the vectors if they were normalized to both have length one. Two vectors with exactly the same orientation have a cosin...
Hamming Distance
Hamming distance is the number of values that are different between two vectors. It is typically used to compare two binary strings of equal length. It can also be used for strings to compare how similar they are to each other by calculating the number of characters that are different from each other.
Manhattan Distance
The Manhattan distance, often called Taxicab distance or City Block distance, calculates the distance between real-valued vectors. Imagine vectors that describe objects on a uniform grid such as a chessboard. Manhattan distance then refers to the distance between two vectors if they could only move right angles. There is no diagonal movement involv...
Chebyshev Distance
Chebyshev distance is defined as the greatest of difference between two vectors along any coordinate dimension. In other words, it is simply the maximum distance along one axis. Due to its nature, it is often referred to as Chessboard distance since the minimum number of moves needed by a king to go from one square to another is equal to Chebyshev ...
Minkowski
Minkowski distance is a bit more intricate measure than most. It is a metric used in Normed vector space (n-dimensional real space), which means that it can be used in a space where distances can be represented as a vector that has a length. This measure has three requirements: 1. Zero Vector — The zero vector has a length of zero whereas every oth...
Jaccard Index
The Jaccard index (or Intersection over Union) is a metric used to calculate the similarity and diversity of sample sets. It is the size of the intersection divided by the size of the union of the sample sets. In practice, it is the total number of similar entities between sets divided by the total number of entities. For example, if two sets have ...
Haversine
Haversine distance is the distance between two points on a sphere given their longitudes and latitudes. It is very similar to Euclidean distance in that it calculates the shortest line between two points. The main difference is that no straight line is possible since the assumption here is that the two points are on a sphere.
Sørensen-Dice Index
The Sørensen-Dice index is very similar to Jaccard index in that it measures the similarity and diversity of sample sets. Although they are calculated similarly the Sørensen-Dice index is a bit more intuitive because it can be seen as the percentage of overlap between two sets, which is a value between 0 and 1:
What is the total distance traveled?
The total distance traveled is the sum of the magnitudes of the individual displacements, 8 m + 3 m = 11 m. The net displacement (the vector sum of the individual displacements), however, is still 5 meters to the left: .
What is the measure zero theorem?

Theorem 1?:IIf X is a finite set, X a subset of ?R?, then X has measure zero.
What is the difference between a zero vector and a positive vector?
Zero Vector — The zero vector has a length of zero whereas every other vector has a positive length. For example, if we travel from one place to another, then that distance is always positive. However, if we travel from one place to itself, then that distance is zero.
What is an example of a set with measure zero?
This Cantor Set in 2D (which has infinitely many points) is another example of a set with measure zero. Figure 2?:MatLab output for n=0,...,4 In the long run the white part of the square will be so thin that it will not take up any area. There will be individual white strings in the carpet, but their area will equal 0.
