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.
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. Basic. Divergence. 1.\:\:\lim _ {x\to 0} (\frac {1} {x}) 2.\:\:\lim _ {x\to 5} (\frac {10} {x-5}) 3.\:\:\lim _ {x\to 1} (\frac {x} {x-1}) 4.\:\:\lim _ {x\to -2} (\frac {1} {x+2}) 5.\:\:\lim _ {x\to 5} (\frac {x} {x^2-25}) 6.\:\:\lim _ {x\to 2}\frac {|x-2|} {x-2}
For each of the following functions f(x), find the real limit as x → ∞ if it exists. If it does not exist, state whether the function tends to infinity, tends to minus infinity, or has no limit at all.
Limits are a very powerful tool in mathematics and are used throughout calculus and beyond. The key idea is that a limit is what I like to call a \behavior operator". A limit will tell you the behavior of a function nearby a point.
The table above gives selected values and limits of the functions 𝑓𝑓, 𝑔𝑔, and ℎ. What is lim 𝑥𝑥→5 ℎ(𝑥𝑥) 𝑓𝑓(𝑥𝑥) + 2𝑔𝑔(𝑥𝑥) −ℎ(5) ? Example 4: Piecewise Functions . Piecewise defined functions and limits 𝑓𝑓(𝑥𝑥) = √11 −𝑥𝑥
