Osculatrix :: Osculatrix (n.) A curve whose contact with a given curve, at a given point, is of a higher order (or involves the equality of a greater number of successive differential coefficients of the ordinates of the curves taken at that point) than that of any other curve of the same kind..
Thermoscope :: Thermoscope (n.) An instrument for indicating changes of temperature without indicating the degree of heat by which it is affected; especially, an instrument contrived by Count Rumford which, as modified by Professor Leslie, was afterward called the differential thermometer..
Quadrature :: Quadrature (a.) 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..
Differential :: Differential (n.) An increment, usually an indefinitely small one, which is given to a variable quantity..
Differentiate :: Differentiate (v. t.) To obtain the differential, or differential coefficient, of; as, to differentiate an algebraic expression, or an equation..
Obeisant :: Obeisant (a.) Ready to obey; reverent; differential; also, servilely submissive..
Differential :: Differential (a.) Of or pertaining to a differential, or to differentials..
Element :: Element (n.) An infinitesimal part of anything of the same nature as the entire magnitude considered; as, in a solid an element may be the infinitesimal portion between any two planes that are separated an indefinitely small distance. In the calculus, element is sometimes used as synonymous with differential..
Differential :: Differential (a.) Relating to differences of motion or leverage; producing effects by such differences; said of mechanism.
Differential :: Differential (n.) One of two coils of conducting wire so related to one another or to a magnet or armature common to both, that one coil produces polar action contrary to that of the other..
Mark :: Mark (n.) A characteristic or essential attribute; a differential.
Integral :: Integral (n.) An expression which, being differentiated, will produce a given differential. See differential Differential, and Integration. Cf. Fluent..
Equation :: Equation (n.) An expression of the condition of equality between two algebraic quantities or sets of quantities, the sign = being placed between them; as, a binomial equation; a quadratic equation; an algebraic equation; a transcendental equation; an exponential equation; a logarithmic equation; a differential equation, etc..

Differential :: Differential (n.) A form of conductor used for dividing and distributing the current to a series of electric lamps so as to maintain equal action in all.
Pyroscope :: Pyroscope (n.) An instrument for measuring the intensity of heat radiating from a fire, or the cooling influence of bodies. It is a differential thermometer, having one bulb coated with gold or silver leaf..
Differentially :: Differentially (adv.) In the way of differentiation.
Fluxion :: Fluxion (n.) A method of analysis developed by Newton, and based on the conception of all magnitudes as generated by motion, and involving in their changes the notion of velocity or rate of change. Its results are the same as those of the differential and integral calculus, from which it differs little except in notation and logical method..
