Natural Log Of 10: Calculation & Uses
The natural logarithm of 10, often written as ln(10), is a fundamental mathematical constant. It represents the power to which the number e (Euler's number, approximately 2.71828) must be raised to equal 10. Understanding and calculating ln(10) is crucial in various fields, including mathematics, physics, engineering, and computer science.
Understanding Natural Logarithms
Natural logarithms are logarithms to the base e. The natural logarithm of a number x is written as ln(x) and is the inverse function of e raised to the power of x (eˣ). In simpler terms:
If eʸ = x, then ln(x) = y
