solutions: http://web.phys.ntnu.no/~ingves/Teaching/TFY4240/Exam/Solution_tfy4240_Dec_2013.pdf
In problem 3 a) I'm supposed to reform the integrand from ##\vec{J}(r',t_r)## to something like ##\vec{J}(r'|\omega)##. In practice, one just extracts the ##t_r## dependent part of the function and writes what remains as ##\vec{J}(r'|\omega)##. But what does my professor mean with that ##"|"## bar? Why not just write the remaining part of the function as ##\vec{J}(r')##?
And excuse me if this is physics notation and not math notation.. In that case pls move this thread to the physics section!
