Quadrature (geometry) - Wikipedia In mathematics, quadrature is a historic term for the computation of areas and is thus used for computation of integrals The word is derived from the Latin quadratus meaning "square" The reason is that, for Ancient Greek mathematicians, the computation of an area consisted of constructing a square of the same area
Quadrature | Integral Calculus, Complex Numbers Geometry - Britannica quadrature, in mathematics, the process of determining the area of a plane geometric figure by dividing it into a collection of shapes of known area (usually rectangles) and then finding the limit (as the divisions become ever finer) of the sum of these areas
QUADRATURE Definition Meaning - Merriam-Webster The meaning of QUADRATURE is a configuration in which two celestial bodies (such as the moon and the sun) have an angular separation of 90 degrees as seen from the earth
Numerical Methods I: Numerical Integration Quadrature quadrature is weakly singular at t = ±1, so that the trapezoidal rule is not applicable Of particular interest are the Gauss-Hermite and the Gauss-Laguerre quadrature, which allow the approximation of integrals over infinite intervals (and even solve exactly for polynomials P E P 2n+1)'
Lecture 14: Quadrature - Kent The approximation of an integral by a numerical method is commonly referred to as quadrature In Calculus one discusses many techniques for determining an antiderivative of f(x) The integral is then computed by evaluating the antiderivative at the endpoints of the interval
Quadrature -- from Wolfram MathWorld Ueberhuber (1997, p 71) uses the word "quadrature" to mean numerical computation of a univariate integral, and "cubature" to mean numerical computation of a multiple integral The word quadrature is
QUADRATURE Definition Meaning - Dictionary. com The process of constructing a square equal in area to a given surface A configuration in which the position of one celestial body is 90° from another celestial body, as measured from a third For example, the half moon lies in quadrature from the Sun when Earth is the reference point
Quadrature - Wikipedia Quadrature (astronomy), the position of a body (moon or planet) such that its elongation is 90° or 270°; i e , the body-earth-sun angle is 90°
