2. (a) Give an example of function f: R-→ R where lim = 0 and lim f(r) = -oo. Motivate. r 00 r0+ For this problem, you may motivate with a graph. (b) Give an example of function g R R where lim =0 and lim g(r) = =00. Motivate. T0+ For this problem, you may motivate with a graph. (c) Prove by using definition 3.3.8 that if lim p(r) -∞ and lim q(x) = 0 then lim (p(r)+ q(r)) = 0. (Hint: E = +5 ) (d) Prove by using Definition 3.4.1 that lim 4 cos(r+a) - 0.
