Moderately Extensive Table of Integral Formulas What follows is a moderately extensive table of integrals formulas, collected from a number of sources and arising in a variety of applications.1 The intent of compiling a table of formulas on-line in this fashion is to facilitate student use across a variety of courses without having to rely on the vagaries of commercial book publishing and frequent release of new editions. Considerable effort has been made (and will continue to be made) to ensure that all of these formulas are correct, but that doesn’t guarantee there are no errors present. If you do find an apparent error, an e-mail to dsabo@bcit.ca would certainly be appreciated. (In all formulas below, symbols {a, b, c, …} from the beginning of the alphabet denote constants, symbols {f, g, h, …} from the middle of the alphabet generally denote functions, and symbols {u, v, x, y, z} from the end of the alphabet denote variables. Because this table is primarily intended for use by “novices”, we have included the constant of integration explicitly using the upper case ‘C’ wherever relevant. In a very few cases, formulas contain a lower case ‘c’ which is to be regarded as some other constant distinct from the constant of integration.) This table is divided into a number of sections, each containing integrals have some distinctive form. Although the sections are not bookmarked in this MS WORD version of the table, we give the list of section headings here in order to aid you in navigating through the table. 1) Elementary Forms 2) Forms Containing a bx (M001 – M010, page 1) (M011 – M023, page 2) 3) Forms Containing a bu 4) Forms containing a 2 u 2 , u 2 a 2 (M024 – M035, page 3) (M036 – M039, page 3) 5) Forms containing u 2 a2 6) Forms containing a2 u 2 7) Forms containing 8) Forms containing 9) 10) 11) 12) 13) 14) u a 2 a 2 u2 2 (M040 – M051, page 4) (M052 – M061, page 4) 3 3 2 (M062 – M070, page 5) 2 (M071 – M078, page 6) Forms containing au 2 bu c Forms containing au n b Trigonometric Functions Inverse Trigonometric Functions Logarithmic Forms Exponential Forms (M079 – M080, page 6) (M081 – M090, page 7) (M091 – M140, page 7) (M141 – M146, page 10) (M147 – M151, page 10) (M152 – M157, page 10) 1.

The numbering of formulas using the prefix ‘M’ for “moderate” from the title is prompted by the thought that some day it might be useful to either produce a somewhat shorter table (or ‘S’) or perhaps even a much more extensive table (or ‘L’).
