WebThe natural logarithm function ln (x) is the inverse function of the exponential function e x. When the natural logarithm function is: f ( x) = ln ( x ), x >0. Then the inverse function of the natural logarithm function is the exponential function: f -1 ( x) = ex. So the natural logarithm of the exponent of x is x: f ( f -1 ( x )) = ln ( ex ) = x. WebIn this tutorial we shall derive the series expansion of the trigonometric function ln ( 1 + x) by using Maclaurin’s series expansion function. Consider the function of the form. f ( x) = ln ( 1 + x) Using x = 0, the given equation function becomes. f ( 0) = ln ( 1 + 0) = ln 1 = 0.
