Induction proof that

n! > n^{3}

for

n \geq 6

, and

\frac{( 2 n ) !}{n ! 2 ^{n}}

is an integer for

n \geq 1

https://math.stackexchange.com/questions/520235/induction-proof-that-n-n3-for-n-ge-6-and-frac2nn-2n-is-an

In part b, you have an interesting expression. What we will prove there is that

\frac{( 2 n ) !}{n ! 2 ^{n}} = 1 \times 3 \times 5 \times \dots \times 2 n - 1,

the product of the first

Yes is a consequence of the following claim: If

∣ r ∣ < 1

then

r^{n} \to 0

. Define

{∣ r^{n} ∣ : n \in N}

, the set is bounded below by zero, let

a = in f {∣ r^{n} ∣ : n \in N}

note that

a \geq 0

Need guidance with inverse laplace transform

https://math.stackexchange.com/q/1149411

We have (through the residue theorem or partial fraction decomposition):

L^{- 1} (\frac{2 s}{( s + 3 ) ^{2} + 4}) = L^{- 1} (\frac{1 - \frac{3}{2} i}{s - ( - 3 - 2 i )} + \frac{1 + \frac{3}{2} i}{s - ( - 3 + 2 i )})
