Assignment #35 (Due Tuesday, 7/26/05)
Posted: Thu Jul 21 17:45:09 MDT 2005

Here are important problems on Integration by Substitution. You want to be real with this method in the first few days of MATH-175.

Section 5.5 has lots of "indefinite integrals" to use to train your eye -- examples 1 - 6 take you through this pretty well.

For "definite integrals" be sure to get with the rule at the top of page 418. Right now, we are oriented around evaluating "definite integrals", that is, we are trying to find the correct numeric value. You don't actually need the page-418 rule to find the right number.

Later on, we'll be interested in using the page-418 rule to transform an integral to a different form, in hopes of seeing some relationship or having an easier computation (see 5.5: 75 -- also 79, 80, 81, 84).

• 5.5: 1-21 odds
• 5.5: 49-69 odds via the page-418 rule (your instructor is really hep on this)
• 5.5: 23-47 odds

Make sure you've grokked and tried the page-418 rule.

• 5.4: 1-15 odds -- so-called "indefinite integrals" are just antiderivatives.
• 5.4: 17-39 odds, especially 27 and 35
• 5.4: 43
• 5.4: 45-51 odds -- displacement analogs and units
• 5.4: 53, 54 -- displacement versus distance travelled.

• 4.10: 11
• 4.10: 13, 15 (trig)
