(updated 10/23/06)

 

1)  2.1, Tangent and Secant lines (instantaneous, average velocity, respectively)

2)  2.2, Limit Definition

            Find Limit using table of values and Graphing

            Ex 1, p. 93

            One-sided Limits (from Left = a-, from Right = a+), Ex1

            Limit Theorem 1, pp. 98, 109

            Ex 7, p 98

3)  2.2, Infinite Limits (+ = upward, - = downward)

            Vertical Asymptotes, p. 100

            Ex 8, p. 98; Ex 10, p.101 (use p. A27)

4)  2.3, Limit Laws, pp. 104-11,

            Ex 1 (a,b,c), p. 105

            Direct Substitution Property (if a in Domain of f), p.107

            Ex 2b, p.106

When a NOT in domain of f (such as Domain restrictions: den 0, even root of -#),

use algebra and Limit Laws to simplify

            Ex 3, p.107 (same as 2.2, Ex 1)

            Ex 6, p. 108

            For 2.3 HW: Read Exs 4-10 and Squeeze Thm

5)  2.4, Optional Read Proof of Limit, pp. 115-116

6)  2.5, 3 criteria for continuous:

                                    1) a in domain of f

                                    2) lim f exists (from left & from right same)

                                    3) lim f(x) = f(a)

            discontinuous if does NOT meet ALL 3 criteria

            Ex 1, p. 124

            3 types discontinuity: removable, infinite, jump; Ex 1

            continuous/discontinuous from left and right, p.125; Ex 1

            time permitting, Ex 2, p. 125

            Read 2.5, Ex 5, p. 128 for HW
