The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718 281 828 459. [1] .

Nov 28, 2025 · The natural logarithm function is defined by ln x = Integral on the interval [1, x ] of ∫ 1 x dt/ t for x > 0; therefore the derivative of the natural logarithm is d/ dx ln x = 1/ x.

Natural logarithm is the logarithm to the base e of a number. Natural logarithm rules, ln (x) rules.

Given how the natural log is described in math books, there’s little “natural” about it: it’s defined as the inverse of e x, a strange enough exponent already. But there’s a fresh, intuitive …

5 days ago · Natural log is the log of a number with base "e" where 'e' is Euler number and its value is 2.718 (approximately). The natural log is defined by the symbol 'ln'. The natural log …

When you're doing simplification or evaluation of logs without a calculator, you will be expected to know that a log with no base written is the common (that is, the base- 10) log, and that ln …

Using ln (x) or log e (x) to refer to the natural log removes this ambiguity. The natural log is used widely throughout mathematics and physics. Logarithms in general are particularly useful for …
