logarithms - The difference between log and ln - Mathematics …
In the early '70s, calculators became widespread. Before then, many books had tables of base-$10$ logarithms in an appendix. Suppose you wanted the logarithm of $123$ The table gave you logarithms of numbers between $1$ and $10$, so you found $\log_{10}1.23= 0.089905\ldots$ and concluded that $\log_{10} 123 = 2.089905\ldots\;{}$.
logarithms - Approximating Logs and Antilogs by hand
There are also methods to compute logarithms of trigonometric functions: trigonometric formulas are very useful to simplify many computations by logarithms. There are also special tables, like a $20$ decimals one in Hoüel tables of logarithms, to compute the log or antilog of a number to $20$ decimal places, with only a very small table (one ...
What algorithm is used by computers to calculate logarithms?
The GNU C library, for example, uses a call to the fyl2x() assembler instruction, which means that logarithms are calculated directly from the hardware. So the question is: what algorithm is used by computers to calculate logarithms?
logarithms - What is the difference between logarithmic decay vs ...
2013年11月8日 · The natural logarithm and exponential are inverses of one another, so the associated slopes will also be inverses.
logarithms - What is the reason to introduce and study logarithmic ...
Logarithms were originally invented to make multiplication (as in, actually computing the product of two numbers by hand) easier. They were developed by one man, John Napier, in the 16th century, specifically as a method for doing by-hand multiplication.

logarithms - Is there an approximation to the natural log function …
Borchardt's algorithm was a popular way to compute logarithms by FORTH programmers in the last century. Another popular method for computing logarithms was to compute the exponential function (inverse of the desired logarithm function) of an initial guess. Exponential function is a rapidly converging power series, so it is quickly computed.
Multiplying two logarithms (Solved) - Mathematics Stack Exchange
2016年4月30日 · I was wondering how one would multiply two logarithms together? Say, for example, that I had: $$\log x·\log 2x < 0$$ How would one solve this? And if it weren't possible, what would its domain be? Thank you! (I've uselessly tried to sum the logs together but that obviously wouldn't work. Was just curious as to what it would give me)
