5.5 Strategy
Since there is no guaranteed method of
doing integrals we proceed as follows
- Draw up a list of as
many as possible “standard integrals” that can be
done. (This has already been done for you and is given in the
formula book.)
- When given a new
integral you must try to rearrange into one of the standard
types. This may involve some or all of the following
- directly
rearrangement (rather trivial);
- substitution;
- integration by
parts;
- special methods for
particular types.
