i found out where i made a mistake with that negative sign. i got it now. thank you so so muchhhhh! happy thanksgiving!

i finally got down to: dt(dt(b)) = laplacian (b) and dt(dt(e))= -laplacian e i still don't understand how that applies to the wave equation.

curl (dt e) = -laplacian (b) dt (curl e) = -laplacian (b) -dt b = -laplacian (b) dt b = laplacian (b) 0 = laplacian (b) and then taking curl of 0.2: dtb = -curl e curl (dt b) = curl (-curl e) dt (curl b) = -curl (curl e) dt (e) = -grad( div e) - laplacian (e) = -grad (0) - laplacian...

taking curl of both side: curl (dt e) = grad (div e) - laplacian (e) curl (dt e) = grad (0) - laplacian (e) i don't know what I'm doing =(

Let respectively b = (b1, b2, b3) and e = (e1, e2, e3) denote the magnetic and electric field in some medium. They are governed by Maxwell’s equations which look as follows: (0.1) \partialte = curl b (0.2) \partialtb = − curl e (0.3) div e = 0 (0.4) div b = 0. Show that each bi and each ei...

how would i solve this? Let respectively b = (b[SIZE="1"]1, b[SIZE="1"]2, b[SIZE="1"]3) and e = (e[SIZE="1"]1, e[SIZE="1"]2, e[SIZE="1"]3) denote the magnetic and electric field in some medium. They are governed by Maxwell’s equations which look as follows: (0.1) d[SIZE="1"]te = curl b (0.2)...
