PC World Forums PDA View Full Version : OT: A question for skilled mathematicians, or am I just thick? Billy T 04-02-2003, 02:16 PM Hi Team I need a hand with a mathematical problem. I'm OK on most routine stuff but my maths education finished in in the 60's and this has me stumped. I have a series of formulae for calculating particular electrical characteristics at varying frequencies including some worked examples (minus the actual working unfortunately). The actual characteristics are unimportant, it is the means of obtaining the result that I can't fathom. The formulae include a decimal fraction i.e. 0.247 or 0.5 in superscript after the number in the same way that we might write a power. Problem is, I haven't the faintest idea how the superscript number is applied and even my fairly switched on daughter (who just passed fifth form NCEA maths while still a 4th former) can't help. All she can do is laugh at my struggles with all the sensitivity that we have come to expect from children when they finally realise that not only do their parents not know everything, sometimes they know nothing at all! :( Here are a few examples with the final result included.

Properties π is an irrational number ; that is, it cannot be written as the ratio of two integers , as was proven in by Johann Heinrich Lambert π is also transcendental , as was proven by Ferdinand von Lindemann in . This means that there is no polynomial with rational (equivalently, integer ) coefficients of which π is a root. An important consequence of the transcendence of π is the fact that it is not constructible . Because the coordinates of all points that can be constructed with ruler and compass are constructible numbers, it is impossible to square the circle , that is, it is impossible to construct, using ruler and compass alone, a square whose area is equal to the area of a given circle. Formulae involving π Geometry appears in many formulae in geometry involving circles and spheres Geometrical shape Formula Circumference of circle of radius r and diameter d Area of circle of radius r Area of ellipse with semiaxes a and b Volume of sphere of radius r and diameter d Surface area of sphere of radius r Volume of cylinder of height h and radius r Surface area of cylinder of height h and radius r Volume of cone of height h and radius r Surface area of cone of height h and radius r (All of these are a consequence of the first one, as the area of a circle can be written as
