Plot of the exponential integral function E n(z) with n=2 in the complex plane from -2-2i to 2+2i with colors created with Mathematica 13.1 function ComplexPlot3D In mathematics, the exponential integral Ei is a special function on the complex plane .
In mathematics, the definite integral ()is the area of the region in the xy-plane bounded by the graph of f, the x-axis, and the lines x = a and x = b, such that area above the x-axis adds to the total, and that below the x-axis subtracts from the total.
Then | | = (()) +, where sgn(x) is the sign function, which takes the values −1, 0, 1 when x is respectively negative, zero or positive. This can be proved by computing the derivative of the right-hand side of the formula, taking into account that the condition on g is here for insuring the continuity of the integral.
Inverse of logarithm integral. Define e x {\displaystyle e^{x}} to be the unique number y > 0 such that ∫ 1 y d t t = x . {\displaystyle \int _{1}^{y}{\frac {dt}{t}}=x.} That is, e x {\displaystyle e^{x}} is the inverse of the natural logarithm function x = ln ( y ) {\displaystyle x=\ln(y)} , which is defined by this integral.
