# Thread: Urgent Help Needed! Fourier Series

1. ## Urgent Help Needed! Fourier Series

Let f(t) be the even function that is zero if t>1, and is given by the straight line 1 -t on [0,1]. Find the Fourier transform of f(t), and use it to evaluate the integrals from 0 to infinity for

(sinc(x))^2 and (sinc(x))^4

Any help is thanked!

Where are you caught at?

I do not understand how to find the function, or how to use a Fourier transform to solve an integral...

Do you think you can help me get started?
