(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem is related to fourier transforms. Since my teacher only cared to spend 2 lectures explaining the whole of this topic, I just cannot get my head around some of the principles involved.

The question is as follows:

Use the Fourier Transform formulas with the function f(t) = t3 when 0 ≤ t < ∞ to show that

What on earth is my starting point?

2. Relevant equations

f(t) = a0/2 + Sum_{n=a}^{infinity}{a_{n}cos(2.n.pi.t/T) + b_{n}sin(2.n.pi.t/T)}

3. The attempt at a solution

I'm sorry, like I said I have no clue where to begin from.

1. What is the difference between fourier series and transform?

2. What would be my starting point for this question? Is this related to fourier series convergence?

3. What is the "fourier transforms" formula?

I'm afraid my teacher has a habit of making things very complicated, and explaining very little...
