Homework Statement


Find the Fourier transform of the following equation.
f1(x) = max(1 - |x|, 0).

Homework Equations



Can anyone say present the function in different way? Since I don't understand what max function does.

The Attempt at a Solution

 
Physics news on Phys.org
Max(a,b) picks the bigger of its arguments'
\max(a,b)=\begin{cases}a & a\geq b\\ b& b>a\end{cases}

I understand what to do next. Thanks alot
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
