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.
Microsoft Word - limits. 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.
• 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.

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. ( x ) l. lim = x → a. g ( x ) m. where m ≠ 0. lim c ⋅ f ( x ) = c ⋅ l. → a. 1. lim = where l ≠ 0. x → a f ( x ) l. Formulas. . n 1 lim 1 + = e.
Limits of functions. mc-TY-limits-2009-1. In this unit, we explain what it means for a function to tend to infinity, to minus infinity, or to a real limit, as x tends to infinity or to minus infinity. We also explain what it means for a function to tend to a real limit as x tends to a given real number. In each case, we give an example of a ...
