5.5 Strategy

Since there is no guaranteed method of doing integrals we proceed as follows

1. 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.)
2. 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
   1. directly rearrangement (rather trivial);
   2. substitution;
   3. integration by parts;
   4. special methods for particular types.
