The function f(x) = e x is called the (natural) exponential function, and is the unique exponential function of type a x equal to its own derivative (f(x) = f ′ (x .

In signal processing, a window function (also known as an apodization function or tapering function) is a mathematical function that is zero-valued outside of some .

The 1-parameter exponential reliability function starts at the value of 100% at , decreases thereafter monotonically and is convex. The 2-parameter exponential .

In differential calculus we learned that the derivative of ln(x) is 1/x. Integration goes the other way: the integral (or antiderivative) of 1/x should be a function .

The principal value of the natural logarithm is implemented in the Wolfram Language as Log[x], which is equivalent to Log[E, x]. This function is illustrated above in .

The derivative of a function is the ratio of the difference of function value f(x) at points x+Δx and x with Δx, when Δx is infinitesimally small. The derivative .

The purpose of this page is to provide resources in the rapidly growing area computer simulation. This site provides a web-enhanced course on computer systems .

Change in natural log ≈ percentage change: The natural logarithm and its base number e have some magical properties, which you may remember from calculus (and which .

The logarithm log_bx for a base b and a number x is defined to be the inverse function of taking b to the power x, i.e., b^x. Therefore, for any x and b, x=log_b(b^x .
