How did napier calculate logarithms
WebThe idea is that we precompute powers of 2 as logarithms. Then, we compute complex multiplications (such as 2²⁵ * 2³⁰ = 33554432 * 1073741824) as additions, and then work out the product ... WebThe basic idea is that square roots are easy to calculate. If you want for example log 10 2 (the number such 2 = 10 log 10 2 ): 10 0.25 = 10 1 / 4 = 1.778... < 2 < 3.162... = 10 1 / 2 …

Web10 de mai. de 2010 · Logarithms were developed in the early 17th century by the Scotsman John Napier and the Englishman Henry Briggs (who later suggested base 10 rather than Napier's strange choice). Their ideas were refined later by Newton, Euler, John Wallis and Johann Bernoulli towards the end of the 17th century. WebWhile in modern terms, the logarithm function can be explained simply as the inverse of the exponential function or as the integral of 1/x, Napier worked decades before calculus was invented, the exponential function was understood, or coordinate geometry was developed by …
