Se konsa, dégradé ki T ap egal a partiel dérivés T osijè de x fwa a vecteur inite w la nan x a direksyon, plis a dérivés partielle de tanperati a fonksyon osijè de y fwa a vecteur inite w la nan y a direksyon, plis a dérivés partielle de tanperati a fonksyon osijè de z fwa vecteur inite w la a nan direksyon z.

So the gradient of T is going to be equal to the partial derivative T with respect to x times the unit vector in the x direction, plus the partial derivative of the temperature function with respect to y times the unit vector in the y direction, plus the partial derivative of the temperature function with respect to z times the unit vector in the z direction.
