1. AP Calculus BC Tuesday, 26 August 2014 OBJECTIVE TSW (1) estimate a limit using a numerical and graphical approach; (2) learn different ways that a limit can fail to exist; and (3) study and use a formal definition of a limit. FORMS DUE (only if they are completed & signed) –Information Sheet & Acknowledgement Sheet (wire basket) I will take batteries and battery money at the beginning of the period. The Student Will

2. Things to Remember in Calculus 1.Angle measures are always in radians, not degrees. 2.Unless directions tell otherwise, long decimals are rounded to three places (using conventional rounding or truncation). 3.Always show work – Calculus is about communicating what you know, not just whether or not you can derive a correct answer.

9. Sec. 1.2: Finding Limits Graphically and Numerically An Introduction to Limits Ex: “The limit as x approaches two of the quantity x cubed minus 8 divided by the quantity x minus 2 is 12” “The limit as x approaches two of f(x) is 12”

10. Sec. 1.2: Finding Limits Graphically and Numerically An Introduction to Limits (informal) Definition: Limit If f (x) becomes arbitrarily close to a single number L as x approaches c from both the left and the right, the limit as x approaches c is L.

11. Sec. 1.2: Finding Limits Graphically and Numerically An Introduction to Limits Ex:

12. Sec. 1.2: Finding Limits Graphically and Numerically An Introduction to Limits Ex: 1

13. Sec. 1.2: Finding Limits Graphically and Numerically An Introduction to Limits Ex: In order for a limit to exist, it must approach a single number L from both sides. DNE

14. An Introduction to Limits Ex: It would appear that the answer is –  but this limit DNE because –  is not a unique number. Sec. 1.2: Finding Limits Graphically and Numerically DNE

16. Sec. 1.2: Finding Limits Graphically and Numerically A Formal Definition of Limit  -  Definition Let f be a function defined on an open interval containing c (except possibly at c) and let L be a . The statement means that for each  > 0,  a  > 0  if A real number Epsilon “There exists” Delta “Such That”
