Mathscene Exponentials and logarithms - Lesson 3
It is not hard to do so by noting that we can calculate logarithms with other base values by dividing the result of the log function with log (base), where log is the natural logarithm function. Therefore, log ( Value, Base ) = log ( Value ) / log ( Base ) .... If you need only an approximate value, one option is to memorize ln x for x from 1 to 10, and then use the formula [math]\ln (a * 10^n) = \ln a + n \ln 10[/math]. 3.8k Views · View 1 …

It's better to work with the functions the language you're using (in this case C++) provides to compute the natural log (which another poster has, I believe already shown to you). But there may be some value in trying this for yourself to see how it works.... Many investments will increase in value and earn a compounded return as time progresses. Investors can use the natural log function to calculate the continuously compounded rate …

4/04/2005 · hey, i was wondering if there was a function you could use to find the ln of a number ( such as: ln(2) ). i've done some searching on google about it, but either i've been using the wrong keywords or i didn't look deep enough, lol. i also tried declaring a double and having this: how to take backup tomtom via280 If you need only an approximate value, one option is to memorize ln x for x from 1 to 10, and then use the formula [math]\ln (a * 10^n) = \ln a + n \ln 10[/math]. 3.8k Views · View 1 …

How To Use The Ln Function On A Calculator
- The functions f(x) = ln x and g(x) = e x cancel each other out when one function is used on the outcome of the other. This is the same as happens with f(x) = log x and g(x) = 10 x or squaring a number then taking the square root of the outcome.
- On a calculator the Natural Logarithm is the "ln" button. Always try to use Natural Logarithms and the Natural Exponential Function whenever possible. The Common Logarithm
- You can enter the function log with base b using either the 1-D or 2-D calling sequence. Similarly, e can also be entered as exp(1) in 1-D. See exp for more about the exponential function.
- The inverse of the natural log (LN) is the exponential function e^x. If y= ln(x) then x=e^y On a calculator functions that are inverse of one another share the same physical key.
