In the realm of mathematics, approximations play a crucial role in simplifying complex calculations and providing quick estimates. Among the most renowned approximations is Euler’s approximation, named after the illustrious mathematician Leonhard Euler. This approximation offers a remarkably accurate way to estimate the value of a function without the need for tedious computations.
What is Euler’s Approximation?
Euler’s approximation formula states that for sufficiently small values of x, the exponential function e^x can be approximated using the expression:
e^x ≈ 1 + x + (x^2) / 2! + (x^3) / 3! + ...
where n! represents the factorial of n.
