F x log b x The derivative of the logarithmic function is given by. Thus yx logax 1 xlna. Eulers formula named after Leonhard Euler is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential functionEulers formula states that for any real number x.
That is the infinitesimal absolute change in f namely f displaystyle f scaled by the current value of f.

In order to evaluate logarithms with a base other than 10 or e e we use the change-of-base formula to rewrite the logarithm as the quotient of logarithms of any other base.
