proof‚ the icing on the cake‚ algebra and geometry playing equal parts. In a similar manner‚ algebraic formulas can also be derived from geometric diagrams. A good example would be the conics. One can’t imagine the conics without their respective geometric diagrams. Not only is geometry tied into algebra in that sense‚ but the fact that the curves had been under scrutiny by the Greeks‚ the greatest exponents of geometry‚ shows their inclination toward some algebra. Numerical approximations for
