an+1 (in context of Error of alternating series)
Error Bound
When doing the limit comparison test, what does the limit look like in order for in to converge?
limit as n approaches infinity of an/bn = L
|an| converges
Answer : what is ____________?
Absolute Convergence
In order for this series to diverge, r > 1 or r = 1
What is a geometric series
1. First derivative test - Show that d/dx = 0, and that f(x) goes from increasing to decreasing
2. Second derivative test - Show that d/dx = 0, and that the second derivative is negative at that point
Find the error bound of the first 6 terms #3
1/5040 OR 0.0002
What should you compare #9 to in order to see if #9 converges or diverges
1/n2 - convergent p series
|an| Diverges but an converges
Answer : What is ________________?
Conditional Convergence
Describe the difference between a sequence and a series
Sequence is a list of numbers
Series adds those numbers
What are the two conditions for continuity at a point p?
1. Limit exists at the point p AKA left = right
2. f(p) = limit as x approaches p
DAILY DOUBLE #6
g(-6)=-12
g(4)=4
g(6)=3
when the series you are looking at looks like another convergent or divergent series you already know.
#2 - Find whether the series diverges, converges conditionally, or converges absolutely
Converges Absolutely
What are the two requirements for the alternating series test?
1) limit as an approaches infinity = 0
2) an+1 is less than or equal to an
Find f(x).
x2+7
Find the number of terms needed to approximate the sum of the series with error less than 0.001 #5
10
Find whether #10 converges or diverges - State what test you used.
Converges
#7 - Find whether the series diverges, converges conditionally, or converges absolutely
Converges Conditionally
This test analyzes the "last term" in an infinite series
Nth term test
A point moves along a straight line with v(t) = 2x+4. It has a know position at t=4 of 10, find its position at t=1.
