Thanks a lot jackmell :)

Hi guys, when writing the Bromwich contour for this integral, as is done in "http://en.wikipedia.org/wiki/Bromwich_integral", would the restriction on \gamma be \gamma > 0 or \gamma > 1 ?

Cheers Matty_t69, now it all makes sense! The plot of the function just makes the question a wee tad more exciting eh? ;)

Ah thanks for that, jackmell, much appreciated! It looks like 3-|z|^2 is not analytic, so the maximum modulus principle must therefore not apply. In situations like this though, we weren't taught how to deal with such things. So would my initial assumption be correct that the maximum of |f| is...

Homework Statement Find the maximum of \left|f\right| on the disc of radius 1 in the Complex Plane, for f(z)=3-\left|z\right|^{2} Homework Equations The maximum modulus principle? The Attempt at a Solution Since |z| is a real number, then surely the maximum must be 3 when z=0...
