When you have a base e , you switch to ln , and again drop the base from your notation. As you can see, log x and ln x are not the same thing! They involve the same concept , and are both logarithms, but they are still different things. What is the difference between log and ln? Thank you in advance. Douglas K. Dec 4, Thanks a lot!

Sep 9, AM views Posted in reply to message from txnelson Or a single overloaded function log , which when given two parameters takes the first as the base, like log 2,x. Add a comment. The difference is which number is the base. Michael Hardy Michael Hardy 1.
If calculating or programming, check a test result before making assumptions. And in the latter case, it may be best to simply ignore a language's built-in log function and use your own so that your code is more portable. Valery Fradkov Valery Fradkov 9 1 1 bronze badge.

Here, the constant e denotes a number that is a transcendental number and an irrational which is approximately equal to the value 2.
Quotient Rule. The natural log of the division of x and y is equal to the difference of the ln of x and ln of y. Reciprocal Rule.
The natural log of the reciprocal of x is equal to the opposite of the ln of x. Power Rule.
