To find the precise point at which it meets the circle, Descartes again considered its determination, or rather the horizontal component unaffected by the collision.

Let the speed before collision be to that after as p: The anaclastic is a refracting surface that directs parallel rays to a single focus; Descartes had generalized the problem to include surfaces that refract rays emanating from a single point and direct them to another point.

And a memoir dating from contains a clear statement of the hydrostatic paradox, later made public by Blaise Pascal.

He does discuss the correspondence further in bk. Here a is the abscissa of the given point on the curve, and the solution follows from equating the coefficients of like powers of x on either side of the desacrtes equation.

Imagine, then, says Descartes, a tennis ball leaving the racket at point A and traveling uniformly along line AB to meet the surface CE at B. To apply algebraic analysis, he then takes the length ABmeasured from the fixed point Aas his first unknown, xand length BC as the second unknown, y. Since, when the ball strikes the surface, it imparts none of its motion to the surface which is immobileit will continue to move at the same speed and hence after a period of time equal to that required to traverse AB will be somewhere on a circle of radius AB about B.

Descartes sought, then, from the beginning of his research a symbolic algebra of pure quantity by which problems of any sort could be analyzed and classified in terms of the constructive techniques required for their most efficient solution.
