A ratio distribution (also known as a quotient distribution) is a probability distribution constructed as the distribution of the ratio of random variables having two other known distributions. Given two (usually independent) random variables X and Y the distribution of the random variable Z that is formed as the ratio Z = X/Y is a ratio distribution.. An example is the Cauchy distribution …

Formal definition. If T is a linear transformation from a vector space V over a field F into itself and v is a nonzero vector in V then v is an eigenvector of T if T(v) is a scalar multiple of v.This can be written as = where λ is a scalar in F known as the eigenvalue characteristic value or characteristic root associated with v.. There is a direct correspondence between n-by-n square …

Plot of the six trigonometric functions the unit circle and a line for the angle θ = 0.7 radians. The points labelled 1 Sec(θ) Csc(θ) represent the length of the line segment from the origin to that point. Sin(θ) Tan(θ) and 1 are the heights to the line starting from the x-axis while Cos…
