The Natural Log Function: Integration Lesson 5.7
Log Rule for Integration • Because • Then we know that • And in general, when u is a differentiable function in x:
Try It Out • Consider these . . .
Finding Area • Given • Determine the area under the curve on the interval [2, 4]
Using Long Division Before Integrating • Use of the log rule is often in disguised form • Do the division on this integrand and alter it's appearance
Using Long Division Before Integrating • Calculator also can be used • Now take the integral
Change of Variables • Consider • Then u = x – 1 and du = dx • But x = u + 1 and x – 2 = u – 1 • So we have • Finish the integration
Integrals of Trig Functions • Note the table of integrals, pg 357 • Use these to do integrals involving trig functions
