-
This section provides more practice in the definitions of trig functions
(e.g. Figure 1) and their identities. Which identities prove to be particular
useful in this section?
-
Why does the author call this technique of trig substitution an example of
``inverse substitution''?
-
What particular power function does this method allow us to eliminate from
integrals?
-
What is the lesson learned in Example 4?
-
What are the definitions of the hyperbolic trig functions and ?
(You'll have to go outside of this section for this one.) Demonstrate that the
two formulas found by the different solution methods in Example 5 are in fact
equivalent, as asserted by the author.
