Logarithmic Integral -- from Wolfram MathWorld

NettetThe logarithmic integral has an integral representation defined for all positive real numbers x ≠ 1 by the definite integral Here, ln denotes the natural logarithm. The function 1/ (ln t) has a singularity at t = 1, and the integral for x > 1 is interpreted as a Cauchy principal value , Offset logarithmic integral [ edit] In mathematics, the sign function or signum function (from signum, Latin for "sign") is a function that returns the sign of a real number. In mathematical notation the sign function is often represented as . charles barkley commercial for fanduel

NettetThe delta function is a generalized function that can be defined as the limit of a class of delta sequences. The delta function is sometimes called "Dirac's delta function" or the "impulse symbol" (Bracewell 1999). It is implemented in the Wolfram Language as DiracDelta [ x ]. NettetThat integral has the function f ( x) = 2 x + 1 as its integrand, which is a simple linear function. That means its graph is just a straight line! As we can see from the integral itself, the limits of integration are 1 and 2, meaning our bounds are straight lines parallel to the y -axis: lines x = 1 and x = 2. harry potter broomstick teacher
