1. Determine an infinite sequence that satisfies the following ... (a) An infinite sequence that is bounded below, decreasing, and convergent (b) An infinite sequence that is bounded above and divergent (c) An infinite sequence that is monotonic and converges to 1 as n → (d) An infinite sequence that is neither increasing nor decreasing and converges to 0 as n + 2. Given the recurrence relation an = 0n-1 +n for n > 2 where a = 1, find...
7. Determine whether the statement is true or false. If it is false, give an example that shows it is false. If it is true, prove it or refer to a theorem. (1) If {an} is divergent, then {an} is unbounded. (2) If {an} is bounded, then {an} is convergent. (3) If {an} converges and {bn} converges, then {an + bn} converges. (4) If {an) is convergent and {bn} is divergent, then {an + bn} is convergent. (5) If {an}...
(c) (5 marks) Give an example of i. a sequence of real numbers that is strictly increasing and converges to zero; ii. a sequence of real numbers that is not monotonic and converges to 2 iii. a sequence of real numbers that is bounded and divergent. (d) (5 marks) Calculate the first four terms in the Laurent series representation of e*.
6. True or False. If the statement is true, explain why using theorems/tests from class, and if the statement is false provide a counter example. (a) If an and are series with positive terms such that is divergent and an <by for all r, then an is divergent. I (b) If a, and be are series with positive terms such that is convergent and an <br for all 17, then an is convergent. (e) If lim 0+1 = 1 then...
1. Let {an}, be a sequence. Write down the formal definition of the following con- cepts. You have already seen some of these in lecture (a) The sequence is convergent b) The sequence is divergent. (c) The sequence is divergent to oo (d) The sequence is divergent to -oo (e) The sequence is increasing f) The sequence is decreasing (g) The sequence is non-decreasing (h) The sequence isn't decreasing (i) The sequence is bounded above (j) The sequence is not...
Problem Give an example of a periodic non-constant function (with a period 2π) such that it is not infinity or zero for all x (meaning for all x, f(x) is a finite positive number). If such a function does not exist, explain why you think so.

please explain each step, give all the reasoning, don’t just give the graph, I have already gotten the graph 1. Sketch the graph of the function that satisfies all the given conditions. (a) f"()>0 on (-0, -4) and (4,oo); f"(x) <0 on (-4,0) and (0,4); lim f()2, lim f(r) -2 ェ→00 (b) f(x) c0 on (-o,-3) and (0, 0) ()>0 on-3,0) f"(z) < 0 on (-00 ,-), f"(z) > 0 on (- 0) and (0,00) f,() = 0, f(-2)--21, f(0)...
