Test these for convergence.
3.
infinity
E...((-1)^n)*(n^3 + 3n)/((n^2) + 7n)
n = 2
4.
infinity
E...ln(n^3)/n^2
n = 2
note: for #3: -((n^2 + 3n))/n) is all to the power of e
Btw, E means sum.
Which tests should I use to solve these?
Test these for convergence.
5.
infinity
E...((n!)^2((2n)!)^2)/((n^2 + 2n)!(n + 1)!)
n = 0
6.
infinity
E...(1 - e ^ -((n^2 + 3n))/n)/(n^2)
n = 3
note: for #3: -((n^2 + 3n))/n) is all to the power of e
Btw, E means sum.
Which tests should I use to solve these?
Test these for convergence.
1.
infinity
E...n!/(n! + 3^n)
n = 0
2.
infinity
E...(n - (1/n))^-n
n = 1
Btw, E means sum.

Homework Statement
How do I find the inverse of these functions step by step?
y= e^-x^3
y= sin(1/x)
I know the solutions but I don't know how to work with these two functions. Does anyone know the steps to finding the inverse of these?
Homework Statement
lim x^3-2x^2+x/tanx
x->0
The Attempt at a Solution
All i know is that tan is going to break up into sinx/cosx so the equation will look like this
lim x^3-2x^2+x/(sinx/cosx)
x->0
I haven't worked with cubic or quadratic functions yet so I don't know...
i am very confused about these problems, my teacher is hard to understand.
a)lim x^2+x+2/x^2-5x+6
..x->3
b)lim (1/x)-1/x^2-1
..x->1
c)lim x^2+2x-6/x^2+3x-2
..x->2
d)lim x^2tanx
..x->0
e)lim x^2sec^2xcot^2x
..x->0
f)lim x^2sin(1/x)
..x->0
g)lim x^2/sin^2x...
