Title: Typos?

In Example 7.2, page 111, to find the inverse of (7.3), one should set  c_1 = 1 and  c_2 = 0 , and not  c_1 = c_2 = 1 as stated?

(2)
In page 114, should the sentence "Equations (7.10) and (7.11) allow us to determine all of the expansions coefficients in (7.9)." refer to Equation (7.8 ) instead?

You are correct. It should be  c_1 = 1 and  c_2 = 0 .  :gr8

You are correct again. It should be (7.8 )  :gr8
