**geometrical**resolution of cubic equations are to be ascribed to the Greeks (for Eutocius assigns to Menaechmus two methods of solving the equation x 3 = a and x 3 = 2a 3), yet the subsequent development by the Arabs must be regarded as one of their most important achievements. - He improved the methods for solving equations, and devised
**geometrical**constructions with the aid of the conic sections. - He possessed clear ideas of indices and the generation of powers, of the negative roots of equations and their
**geometrical**interpretation, and was the first to use the term imaginary roots. - So far the development of algebra and geometry had been mutually independent, except for a few isolated applications of
**geometrical**constructions to the solution of algebraical problems. Certain minds had long suspected the advantages which would accrue from the unrestricted application of algebra to geometry, but it was not until the advent of the philosopher Rene Descartes that the co-ordination was effected. - The
**geometrical**interpretation of imaginary quantities had a far-reaching influence on the development of symbolic algebras. - If the point under consideration be so far away from the
**geometrical**shadow that a large number of the earlier zones are complete, then the illumination, determined sensibly by the first zone, is the same as if there were no obstruction at all. - If, on the other hand, the point be well immersed in the
**geometrical**shadow, the earlier zones are altogether missing, and, instead of a series of terms beginning with finite numerical magnitude and gradually diminishing to zero, we have now to deal with one of which the terms diminish to zero at both ends. - In such experiments the narrowness of the zones renders necessary a pretty close approximation to the
**geometrical**conditions. - The expression (5) gives the illumination at due to that part of the complete image whose

**geometrical**figures certain laws of physical forces. - In his youth he went to the continent and taught mathematics at Paris, where he published or edited, between the years 1612 and 1619, various
**geometrical**and algebraical tracts, which are conspicuous for their ingenuity and elegance. - This involved not only the
