Logarithmic Integral Function Pdf The logarithmic integral in this chapter we discuss the argument principle and develop several of its consequences. in section 1 we derive the argument principle from the residue theorem, and we use the argument principle to locate the zeros of analytic functions. sections 2 through 5 can be viewed as a study of how. = ln |f| c to determine the integral. then repeat the integral, using algebra to simplify the integrand before integration.
Week 14 Part 1 Integrals Yielding The Natural Logarithmic Function Pdf Integral Section 5.2 the natural logarithmic function: integration • use the log rule for integration to integrate a rational function. • integrate trigonometric functions. Sine integral, cosine integral, and exponential integral, p. 262 in the proceed ings of the royal society of london, from june 17, 1869 to june 16, 1870, vol. xviii, 1870.

I the graph of the natural logarithm. i integrals involving logarithms. i logarithmic differentiation. Let us look more carefully at the logarithmic integral. as logf(z) = lnjf(z)j iargf(z) we have dlogf(z) = dlnjf(z)j dargf(z): therefore 1 2ˇi z dlogf(z) = 1 2ˇi z dlnjf(z)j 1 2ˇ z dargf(z): now the rst integral on the rhs is not so complicated. as there is no ambiguity in the de nition of lnjf(z)jit follows that z dlnjf(z)j= lnjf( )j lnjf. Using the derivative of the natural logarithmic function to obtain an antiderivative: example 1: find the derivative of gx x ()ln. note that f ()ln xx has the same derivative as gx x ()ln. Although these right sides are the lineal primitive functions of log||logx, since both zeros of xnlog||logx and ei()nlogx are 0, zeros of the right sides are all 0. therfore, the lineal higher primitive function of log||logx can be expressed by the higher integral with a fixed lower limit 0. formula 14.5.1 when ei()x = x t et.
