AP Calculus BC Tuesday, 25 August 2015 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) The Student Will

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.

Trigonometric Notes Sheet You need to have these memorized for Friday’s quiz and for the rest of the year: 5.Unit Circle a.Special angles (in radians) b.Sines, cosines, tangents, secants, cosecants, and cotangents of each special angle 6.Double-Angle Formulas a.sin 2u b.cos 2u

Trigonometric Notes Sheet You need to have these memorized for Friday’s quiz and for the rest of the year: 7.Power-Reducing Formulas a.sin 2 u b.cos 2 u

Sec. 2.2: Definitions of Limits An Introduction to Limits Ex: In order for a limit to exist, it must approach a single number L from both sides. DNE

An Introduction to Limits Ex: It would appear that the answer is –  but this limit DNE because –  is not a unique number. Sec. 2.2: Definitions of Limits DNE
