where can i go to find information on logarithms?

Answer 1

What information do you need on logarithms? They are pretty self explanatory and there are only a handful of rules

log (a⋅b) = log (a) + log (b)
log (a / b) = log (a) − log (b)
log (aⁿ) = n ⋅ log (a)

"log", without a subscript, is the common logarithm, or base 10 logarithm

"ln" is the natural logarithm, or base ℮ (Euler's constant), logarithm ( log_{e} )

You cannot have a logarithm whose base has the absolute value of 1. ( that includes 1, −1, i, −i, ½√2 + ½⋅i⋅√2 ).

The logarithm of 0 is undefined.

The logarithm of 1 is always 0.

Base conversion from one base to another:
log_{a} (b) = log_{c} (b) / log_{c} (a)

logarithms of negatives and imaginary values are permitted, only if you allow for complex solutions.

Then there are properties that we discover in higher level maths.
∂/∂x ln (x) = 1 / x
To name only one.

Essentially, everything you need to know, for basic algebraic manipulations, about logarithms are right here in this post.

Some of these are in fact based on one another. The more complex rules can easily be proven from simpler rules.

Expanding on these algebraic rules would only be redundancies or special cases.

Answer 2

Logarithms have been used to do math in the previous pcs and handheld calculators got here alongside. for example in case you're taking the logarithm of a variety, divide that via 2 and then convert the logarithm lower back right into a variety you have the sq. root of the unique variety. handheld calculators use the algotirhm in lots of circumstances as that's user-friendly to probram in a table of logarithms.

Answer 3

For the basic information check wikipedia:
http://en.wikipedia.org/wiki/Logarithm
Pretty good and concise introduction.

For more advanced topics go to Wolfram.com
