The speculations of algebra, the doctrine of infinites, and the quadrature of curves should not intrench upon our studies of morality. Isaac Watts, Improvement of the Mind.

It is full moon, when the earth being between the sun and moon, we see all the enlightened part of the moon; new moon, when the moon being between us and the sun, its enlightened part is turned from us; and half moon, when the moon being in the quadratures, we see but half the enlightened part. John Locke.

All things parted by th’ empyreal bounds,
His quadrature from thy orbicular world. John Milton.

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

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

the position of one heavenly body in respect to another when distant from it 90¡, or a quarter of a circle, as the moon when at an equal distance from the points of conjunction and opposition.

Waves or periodic motions the angle of lag of one of which, with reference to one in advance of it, is 90°, are said to be in quadrature with each other. [Transcriber's note: If the voltage and current of a power line are in quadrature, the power factor is zero (cos(90°) = 0)  and no real power is delivered to the load.]
