The correct and most appropriate answer to a multiple-choice question will be, in each case, just one of the seven choices (A), (B), (C), (D), (E), (F), or (G). Answer all multiple-choice questions on the answer sheet, which is page 14 of this exam.
Definition: Let f be a function of two variables defined for all points "near" (a,b) but possibly not defined at the point (a,b). We say the . limit of f(x,y) as (x,y) approaches (a,b) is L, written as. lim f(x,y) = L , (x,y)!(a,b) if the distance from f(x,y) to L, | f(x,y) – L | , can be made arbitrarily .
LIMITS BY STANDARD EXPANSIONS. Write down the first two non zero terms in the expansions of sin3x and cos2x . Hence find the exact value of. 3 x cos2 x − sin3 x . lim 3 . x → 0 3 x . sin3 x ≈ 3 x − 9 x 3 , cos2 x ≈ 1 − 2 x 2 , − 1. 2 2. Use standard expansions of functions to find the value of the following limit.
Limits and Derivatives Formulas. 1. Limits. Properties. if lim f ( x ) = l and lim g ( x ) = m , then. x → a x → a. lim [ f ( x ) ± g ( x ) ] = l ± m. x → a. lim [ f ( x ) ⋅ g ( x ) ] = l ⋅ m. → a.

• Distinguish between limit values and function values at a point. • Understand the use of neighborhoods and punctured neighborhoods in the evaluation of one-sided and two-sided limits. • Evaluate some limits involving piecewise-defined functions. PART A: THE LIMIT OF A FUNCTION AT A POINT
Limits. Definitions Precise Definition : We say lim f ( x ) = L if Limit at Infinity : We say lim f x = L if we. x a (. ) x ®¥. for every e > 0 there is a d > 0 such that can make f ( x ) as close to L as we want by whenever 0 < x - a < d then f ( x ) - L < e . taking x large enough and positive.
