A typical modern trig table. The ancient Babylonians had an advantage over our current counting system because they use base-60, instead of the base-10 system that we use.

Integration is the inverse of differentiation of algebraic and trigonometric expressions involving brackets and powers. This can solve differential equations and evaluate definite integrals.

Formulas are derived giving the vector potential and the magnetic field components of a general coil of rectangular cross section and constant winding density. The solution is given in a cylindrical ...
