Unformatted text preview: (d) Radicals (i) √ ± x 2 ± a 2- use trigonometric substitution (ii) n √ ax + b- use rationalization substitution u = n √ ax + b Strategy for Integration 4. Try Again (a) Try substitution , including non-obvious ones (b) Try parts , e.g. on single functions such as ln x (c) Manipulate the integrand , like in step 1. but more substantial (d) Relate the problem to previous problems , remember previously calculated integrals and previously used tricks (e) Use several methods , such as several substitutions, or substitutions and integration by parts...
