Basic IntegrationRules Lesson 8.1
Fitting Integrals to Basic Rules • Consider these similar integrals • Which one uses … • The log rule • The arctangent rule • The rewrite with long division principle
Try It Out • Decide which principle to apply …
The Log Rule in Disguise • Consider • The quotient suggests possible Log Rule, but the du = exis not present • We can manipulate this to make the Log Rule apply • Add and subtract ex in the numerator
The Power Rule in Disguise • Here's another integral that doesn't seem to fit the basic options • What are the options for u ? • Best choice is
The Power Rule in Disguise • Thenbecomes and power rule applies • Note review of basic integration rules pg 520 • Note procedures for fitting integrands to basic rules, pg 521
Disguises with Trig Identities • What rules might this fit? • Note that tan2 u is not on the list … • However sec2uis on the list • This suggests one of the pythagorean identities and we have
