I keep doing questions on fourier transforms where the 1/2pi isn't there.(adsbygoogle = window.adsbygoogle || []).push({});

Example:

[tex]

F\left[\frac{\partial^2u\left(x,y\right)}{\partial x^2}\right]

[/tex]

for which I thought the next step would be

[tex]

\[

\frac{1}{2\pi}\int^{\infty}_{-\infty}\frac{\partial^2u\left(x,y\right)}{\partial x^2} e^{-isx} dx

\[

[/tex]

but I keep finding it written in my answer booklet thing

[tex]

\[

\int^{\infty}_{-\infty}\frac{\partial^2u\left(x,y\right)}{\partial x^2} e^{-isx} dx

\[

[/tex]

I have found one example in my book where the 1/2pi appears, why does it not feature in these examples?

Cheers!
