1 day ago · f(X) = X n + a n−1 X n−1 + ⋯ + a 0 (where f is regarded as a polynomial in E(a 0, ..., a n−1), for some indeterminates a i, E is any field, and n ≥ 5). The tensor product of fields is not usually a field. For example, a finite extension F / E of degree n is a Galois extension if and only if there is an isomorphism of F-algebras F ⊗ ...
1 day ago · In other words, multiply the remainder by 100 and add the two digits. This will be the current value c. Find p, y and x, as follows: Let p be the part of the root found so far, ignoring any decimal point. (For the first step, p = 0.) Determine the greatest digit x such that (+). We will use a new variable y = x(20p + x).
1 day ago · In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.
1 day ago · A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.

1 day ago · Discrete cosine transform. A discrete cosine transform ( DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. The DCT, first proposed by Nasir Ahmed in 1972, is a widely used transformation technique in signal processing and data compression.
