The invention of analytic geometry, after differential and necessary calculus, became the maximum critical mathematical improvement of the seventeenth century. Originating inside the work of French mathematicians Viet, Fermat, and Descartes, it had hooked up itself as a major application of mathematical studies with the aid of the center of the century.
Two developments in current mathematics brought on the upward thrust of analytic geometry. First, there has been a developing hobby in curves, ensuing in part from the healing and Latin translation of the classical texts of Apollonius, Archimedes, and Pappus, and partially from the growing importance of curves in implemented fields including astronomy, mechanics, optics, and astronomy. And stereometry. The 2d became the emergence a century in advance of an established algebraic practice in the paintings of Italian and German algebraists and the following shaping via the Viet as a powerful mathematical tool at the flip of the century.

Viet became an outstanding representative of the humanist motion in arithmetic that set itself the assignment of restoring and furthering the achievements of classical Greek geometers. In his In Arteum Analyticum Isagoge (1591; “Introduction to the Analytic Arts”), Viet proposed new algebraic strategies, as part of his program to rediscover the method of analysis utilized by ancient Greek mathematicians. Which employed variables, constants, and equations. , however, he saw it as a development of the historical technique, a method that he compared to the geometric evaluation contained in Book VII of Pappas’ collection, to Diophantus’s Arithmetic Analysis of Arithmetic. Pappas used an analytical approach to find out theorems and formulate issues; In analysis, from assessment to synthesis, one proceeds from what he seeks until he arrives at something recognized. Approaching a mathematics problem via determining an equation between known and unknown magnitudes and then solving for the unknowns, followed an “analytical” system, Viette argued.

Viet added the concept of algebraic variables, which he represented using a capital vowel (a, e, i, o, u) as well as the concept of a parameter (an unspecified steady quantity), which he denoted as a capital consonant (b, c). ) become shown. , D, and so on). In his machine, the equation 5BA2 – 2CA + A3 = D, A + A in a Cube Equator D Solido would appear as B5 in A Quad – C Plano 2.
Viet upheld the classical principle of symmetry, according to which all phrases introduced together need to be of identical measurement. In the above equation, for instance, every time has the dimension of a strong or a cube; Thus, the constant C, which represents a plane, combines with A to form a quantity with dimensions of a strong.
It must be noted that the symbol A in Viet’s scheme is a part of the expression for the item obtained via working on the significance denoted with the aid of A. Thus, operations on portions represented via variables are meditated in the algebraic notation itself. This innovation, which appeared by historians of arithmetic as a first-rate conceptual boost in algebra, facilitated a look at symbolic answers to algebraic equations and produced the first aware concept of equations.
After Viette’s demise, the analytical art was applied to the observation of curves by his countrymen Fermat and Descartes. Both men had been stimulated with the aid of the same intention, to use new algebraic strategies to the principle of loci of Apollonius preserved in the collection of Pappus. The most well-known of these problems concerned locating a traced curve or space from a point whose distance from several fixed strains satisfied a given relation.
Fermat followed Viète’s notation in his paper “Ad Locos Planos et Solidos Isagoge” (1636; “Introduction to Plane and Solid Loci”). The name of the paper refers back to the historical classification of curves as aircraft (straight lines, circles), strong (ellipse, parabola, and hyperbola), or linear (curves defined kinetically or by way of a locus function). Fermat takes into consideration an equation between two variables. One of the variables represents a line measured horizontally from a given starting point, whilst the opposite represents a line positioned on the quit of the primary line and bent at a positive angle to the horizontal. As the primary variable varied in value, the second one assumed the price determined by the equation, and the endpoint of the second line traced a curve in area.
