I wanted to know whether it was possible for Mathematica to give you an exact read out of the maximum and minimum y-axis values on a 2D plot?(adsbygoogle = window.adsbygoogle || []).push({});

I have tried Maximize function but it seems to think there are imaginery parts in my function (which there are not or how would it plot the function in the first place) and so refuses to work out the maximum. Even if I try and Maximise the real part of my function it doesn't work.

What I'm looking for is a way to plot the graph and then simply read off the max and min values with speed and accuracy and perhaps even form another plot of contrast (max-min) vs another variable in the formula.

Thanks
