1 2 ln x

The natural logarithm of a number is its logarithm to the base of the mathematical constant ewhich is an irrational and transcendental number approximately equal to 2. This is done particularly when the argument to the logarithm is not a single symbol, so as to prevent ambiguity. The 1 2 ln x logarithm of x is the power to which e would have to be raised to equal x. For example, ln 7.

Other High School. If you're taking a high school or college math class, you'll likely cover natural logs. But what are natural logs? What is ln? Why does the letter e keep showing up? Natural logs may seem difficult, but once you understand a few key natural log rules, you'll be able to easily solve even very complicated-looking problems.

.

In other words, it calculates the natural logarithm. But, what is the natural logarithm , ln x, of a given number x? This is the power the number e has to be raised to in order to result in a given number x. Like all other logarithms, the natural logarithm of x returns the power, or exponent, to which a given base e must be raised to yield back the number x. It is easier to understand this notion when the base is an integer, for example, 2 or In the case of the natural logarithm, this is somewhat less intuitive because its base, e, is not an integer. This equality can be stated in terms of the natural logarithm in the following way, which you can check by using the ln calculator:. You can check out the correctness of the above results by using our natural log calculator and the exponent calculator. Additionally, to better grasp the interplay between the exponential and logarithm functions , you may want to check the exponent calculator along with the log calculator. One way of denoting the natural logarithm is log e.

Categories : Logarithms Elementary special functions E mathematical constant Unary operations. ISBN However, the natural logarithms of much larger numbers can easily be computed, by repeatedly adding those of smaller numbers, with similarly rapid convergence. This keeps the argument, the result, and intermediate steps all close to zero where they can be most accurately represented as floating-point numbers. Note that we have not yet proved that this statement is true. For example, ln 7. The complex logarithm can only be single-valued on the cut plane.
