main ideas and results for limits of functions of one variable and reworking a few limit problems. The main focus of this section is on functions of two variables since it is still possible to visualize these functions and to work geometrically, but the end of this section includes extensions to functions of three and more variables.
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.
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.
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.
• We will use limits to analyze asymptotic behaviors of functions and their graphs. • Limits will be formally defined near the end of the chapter. • Continuity of a function (at a point and on an interval) will be defined using limits.
