Hi there to all. I am stuck and i want some help to clear my view
When you have defined the vector S=(S_x ,S_y ,S_z) and you have a function like
E_h = k1 (S_x^2 S_y^2 + S_x^2 S_z^2 + S_y^2 S_z^2) + k2 S_z - k3 S_x S_y
and you try to calculate -\frac{\partial E_h}{\partial S} what the result is?
(the S is vector)
My mind has been blocked... help me please.
