• Due any time between now and 20 September 2013.
Things to Remember in Calculus
• Angle measures are always in radians, not degrees.
• Unless directions tell otherwise, long decimals are rounded to three places (using conventional rounding or truncation).
• Always show work – Calculus is about communicating what you know, not just whether or not you can derive a correct answer.

• Definition of the Six Trig Functions (including the pictures)
• Right Triangle Definitions
• Circular Function Definitions
• Reciprocal Identities
• Tangent and Cotangent Identities
• Pythagorean Identities
Trigonometric Notes Sheet

You need to have these memorized for Friday’s quiz and for the rest of the year:

• 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”

• 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.

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 Lfrom 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.

• 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

“There exists”
