Homework Statement
Q1 Are the following sequences divergent or convergent as n tends to infinity.
A: [itex]\frac{5n+2}{n-1}[/itex]
B: [itex]tan^{-1}(n)[/itex]
Homework Equations
The Attempt at a Solution
Really not sure how to show this mathematically, or even if what I have done is correct.
Part A:
[tex]
\frac{5n+2}{n-1}=12,\frac{17}{2},\frac{22}{3},\frac{27}{4}...\\[/tex]
So it looks as tho it converges to 0 as n tends to infinity.
Part B:
[tex]
tan^{-1}(n) = \frac{\pi}{4},1.107,1.25...
[/tex]
From messing on the calculator I can see that it tends to pi/2 as n tends to infinity but don't know how to show it mathmatically.
I would really appreciate any feedback or advice :)
