[3] In 2009, the Bolivian government approved a deal to purchase 6 K-8P aircraft for use in anti-drug operations. [4]
The theory of optimal control is concerned with operating a dynamic system at minimum cost. The case where the system dynamics are described by a set of linear differential equations and the cost is described by a quadratic function is called the LQ problem.
Analytic continuation of natural logarithm (imaginary part) Analytic continuation is a technique to extend the domain of a given analytic function.Analytic continuation often succeeds in defining further values of a function, for example in a new region where an infinite series representation in terms of which it is initially defined becomes divergent.
Figure 1. Plots of quadratic function y = ax 2 + bx + c, varying each coefficient separately while the other coefficients are fixed (at values a = 1, b = 0, c = 0). A quadratic equation whose coefficients are real numbers can have either zero, one, or two distinct real-valued solutions, also called roots.
In probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables.
This offer was accepted and K IX arrived in Sydney for repairs on 12 May. On 1 June K IX was damaged by a torpedo explosion during the attack on Sydney Harbour. [2] K IX was decommissioned from the Royal Netherlands Navy on 25 July 1942 and following extensive repairs was commissioned into the Royal Australian Navy as HMAS K9 on 22 June 1943. [3]
K with stroke (ę, ę) is a letter of the Latin alphabet, derived from K with the addition of a bar through the letter. It was used in Latin as an abbreviation for words that start with k . In Old Norse it was used for "konungr" (king) or to abbreviate the word "skulu" (shall) to "sę".
