- What is the point of logarithms? How are they used?
Logarithms are a convenient way to express large numbers (The base-10 logarithm of a number is roughly the number of digits in that number, for example ) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division (This benefit is slightly less important today ) Lots of things "decay logarithmically"
- What algorithm is used by computers to calculate logarithms?
I would like to know how logarithms are calculated by computers The GNU C library, for example, uses a call to the fyl2x() assembler instruction, which means that logarithms are calculated directl
- What are the parts of a logarithm called? [duplicate]
$\begingroup$ I had "the logarithm of a number is the index to which the base is raised to equal that number" drilled into me 60 years ago It's still helpful when I need a reminder what does what It's still helpful when I need a reminder what does what
- How is $\\ln$ pronounced by English speakers?
It is unfortunate that secondary-school algebra textbooks teach students that "log" with no subscript always means the base-$10$ logarithm Since the natural logarithm is indeed the natural logarithm to use in calculus, it is written as $\log$ with no subscript Some mathematicians write it as $\ln$ but still understand $\log$ written by others
- Calculate logarithms by hand - Mathematics Stack Exchange
I'm thinking of making a table of logarithms ranging from 100-999 with 5 significant digits By pen and paper that is I'm doing this old school What first came to mind was to use $\\log(ab) = \\lo
- Why are logarithms not defined for 0 and negatives?
I can raise $0$ to the power of one, and I would get $0$ Also $-1$ to the power of $3$ would give me $-1$ I think only some logarithms (e g log to the base $10$) aren't defined for $0$ and negat
