Re: Confused by a derivation.



Sorry, I omitted the " = 0 " in the corrected equations. I have completed

Of course I made two boo-boos:
E = (A/2*epsilon)*(q1 -q2 -q3 -q4) =0
should read: E = (q1-q2-q3-q4)/(A*2epsilon) =0 and
E = (A/2*epsilon)*(q1 +q2 +q3 -q4) =0.
should read: E = (q1+q2+q3-q4)/(A*2epsilon)=0
. . .
