 | | Calculation of a square root by hand is a little like long-hand division. |
 | | That is, we have improved our knowledge of the square root by one digit, B. We take whatever remains, scale again by 100, by bringing down two more digits, and repeat the process. |
 | | Note: In computers and hand-held calculators, square root, sine, cosine, and other transcendental functions are calculated with sophisticated functions based on the Newton-Raphson method, sometimes called Newton's method. |
