Determine whether the sequence is divergent or convergent. If
it is convergent, evaluate its limit.
(If it diverges to infinity, state your answer as inf . If it
diverges to negative infinity, state your answer as -inf . If it
diverges without being infinity or negative infinity, state your
answer...

Hiromi took a 250 mg dose of a pain killer before going to bed
last night. Every hour, 6% of the drug is metabolized. Let an be
the amount of the drug remaining in Hiromi’s body n hours after she
swallowed it. Note: a0 = 250. Answer the following questions.
a. Write the first four terms of the sequence {an}. So, you are
figuring out a1, a2, a3, and a4. You may give exact answers or
answers rounded to the...

Consider
lim (x, y)→(0, 0)
x2 + y2
xy
(see figure).
(a) Determine (if possible) the limit along any line of the
form
y = ax.
(Assume
a ≠ 0.
If an answer does not exist, enter DNE.)
(b) Does the limit exist? Explain.
Yes, the limit exists. The limit is the same regardless of which
path is taken.No, the limit does not exist. Different paths result
in different limits.

Consider the series ∑n=1 ∞ an
where
an=(5n+5)^(9n+1)/
12^n
In this problem you must attempt to use the Ratio Test to decide
whether the series converges.
Compute
L= lim n→∞
∣∣∣an+1/an∣∣
Enter the numerical value of the limit L if it converges, INF if
the limit for L diverges to infinity, MINF if it diverges to
negative infinity, or DIV if it diverges but not to infinity or
negative infinity.
L=

3. Consider the following property: for any ε>0, there exists
N∈N so that whenever n≥N,|u_n+1−u_n|<ε.
What is the difference between this property and the definition
of a Cauchy sequence?
Find a convergent sequence which has this property.
Find a divergent sequence which has this property. (Hint: can
you think of a function f(x) which grows to infinity very
slowly? Then try a_n=f(n).

(1 point) The three series ∑An, ∑Bn, and ∑Cn have terms
An=1/n^8,Bn=1/n^5,Cn=1/n. Use the Limit Comparison Test to compare
the following series to any of the above series. For each of the
series below, you must enter two letters. The first is the letter
(A,B, or C) of the series above that it can be legally compared to
with the Limit Comparison Test. The second is C if the given series
converges, or D if it diverges. So for instance,...
