This material gives a straightforward introduction to techniques of integration, which is one of the most difficult areas of calculus. A lot of completely worked examples are used to introduce methods of integration and to demonstrate problem-solving techniques. The topics are written as self-guided tutorials. Each page contains necessary definitions and formulas, which are illustrated by typical problems with detailed solutions.
