would anyone agree that the question is asking for the electron binding energy and that i was trying to find the wrong thing? im still stuck with this. Thanks Sean

Homework Statement In a crystal lattice of MgO, the Mg is surrounded by 6 Oxygen atoms as shown. Assume that the ions all behave as point charges. If the system behaves as though there were separate interactions between Mg and each of the Oxygen ions what is the total binding energy of...

oh, cool, thanks. missed that completely. thanks again

you mean 1/s^n, example 2.7a i don't really see how that matches s/((s+1)^(2) +4) would it be possible for you to explain

thanks lanedance i don't believe that i am expected to derive it myself as I am sure i read somewhere that i wasnt expected to for this course. i have looked through a few simular tables without much luck I am afraid. it may be possible that i messed up further up the question and...

Homework Statement hi guys, i need to find the inverse Laplace transform of s/((s+1)^(2) +4) the acual question is an IVP, i have worked trough it and am just about finished but i am stuck on this transform. how would you go about getting this into a form that can be transformed like...
