Quadrature is a mathematical term referring to the process of determining the area under a curve, or more generally, finding a definite integral. This term is often used in numerical integration and is particularly associated with approximating the value of an integral using finite processes. In classical antiquity, it also referred to the geometric problem of squaring the circle.
the act of squaring; the finding of a square having the same area as some given curvilinear figure; as, the quadrature of a circle; the operation of finding an expression for the area of a figure bounded wholly or in part by a curved line, as by a curve, two ordinates, and the axis of abscissas
a quadrate; a square
the integral used in obtaining the area bounded by a curve; hence, the definite integral of the product of any function of one variable into the differential of that variable
