Section 2.3: Calculating Limits Using the Limit Laws Instructor: Ms. Hoa Nguyen (nguyen@scs.fsu.edu) Limit Laws Suppose that c is a constant and the limits lim x a f ( x ) and lim x a g ( x ) exist. Then 1) Limit of sum/ difference = Sum/ Difference of limits: lim x a [ f ( x ) ± g ( x )] = lim x a f ( x ) ± lim x a g ( x ). 2) Limit of constant times function = constant times limit of function: lim x a [ cf ( x )] = c lim x a f ( x ). 3) Limit of product/ quotient = product/ quotient of limits: lim x a [ f ( x ) · g ( x )] = lim x a f ( x ) · lim x a g ( x ). lim x a f ( x ) g ( x ) = lim x a f ( x ) lim x a g ( x ) if lim x a g ( x ) 6 = 0. 4) Power law: lim x a [ f ( x )] n = [lim x a f ( x )] n where n is a positive integer. 5) Inequality: f ( x ) g ( x ) when x a =
