How does one find the Fourier Transform of 1?(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\mathscr{F}\{1\}=\mathcal{F}\{1\}=\int\limits_{-\infty}^{\infty}{e}^{-i \omega t} \mbox{d}t=?[/tex]

I tried to solve it and came up with

[tex]\sqrt{\frac{2}{\pi}}\frac{1}{\omega}\lim_{t \rightarrow \infty}\sin\left(\omega t\right) [/tex]

but that is indeterminate whereas actual answer is

[tex]\sqrt{2\pi}\delta\left(\omega\right)[/tex]

So how does one actually solve this Fourier Transform.

Thanks in advance.
