26 Does anyone know a closed form expression for the Taylor series of the function f ( x) = log ( x) where log ( x) denotes the natural logarithm function? logarithms taylor-expansion Share Cite Follow asked Nov 29, 2013 at 0:37 Jamie Sethian 259 1 4 4 1 wolframalpha.com/input/?i=taylor+log%28x%29 - Amzoti Nov 29, 2013 at 0:40 Logarithms are useful for solving equations in which the unknown appears as the exponent of some other quantity. For example, logarithms are used to solve for the half-life, decay constant, or unknown time in exponential decay problems.

Log 3 = log 2 + log 1.5, because 3 = 2.1,5. So, find log 1.5 and add it to log 2. Log 1.5uses x = 1/5 and it converges faster than log 2 did. Now you have a quicker reliable 6-figure value for log 3. In the example above, you tackle finding all the logs for integers up to 10. Notice the short cuts you can take. Applications of Natural Log Series. Radiation lifetime in a cavity. Index. HyperPhysics **** HyperMath ***** Calculus. R Nave. Logarithmic Series Definition An expansion for log e (1 + x) as a series of powers of x which is valid only, when |x|<1. Expansion of logarithmic series Expansion of log e (1 + x) if |x|<1 then Replacing x by −x in the logarithmic series, we get Some Important results from logarithmic series In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3.

Taylor series - Wikipedia Taylor series As the degree of the Taylor polynomial rises, it approaches the correct function. This image shows sin x and its Taylor approximations by polynomials of degree 1, 3, 5, 7, 9, 11, and 13 at x = 0.

A Taylor series for log(x) is a mathematical representation of the natural logarithm function using a polynomial. It allows us to approximate the value of log(x) at any given point by using a series of terms that are derived from the function's derivatives at a specific point. 2. What is the formula for a Taylor series for log(x)?

Using the Taylor series: Gives the result: EDIT: If anyone stumbles across this an alternative way to evaluate the natural logarithm of some real number is to use numerical integration (e.g. Riemann sum, midpoint rule, trapezoid rule, Simpson's rule etc) to evaluate the integral that is often used to define the natural logarithm; python python-3.x Power Series Expansion for Logarithm of 1 + x Contents 1 Theorem 1.1 Corollary 2 Proof 3 Sources Theorem The Newton-Mercator series defines the natural logarithm function as a power series expansion : valid for all x ∈ R such that − 1 < x ≤ 1 .
