Question

TuteeHUB · Accepted Answer

(  frac{d  phi}{dt}+  frac{d}{dx}(  Gamma  frac{d  phi}{dx})+S=0  )

TuteeHUB · Answer

div(  grad  )+S=0

TuteeHUB · Answer

(  frac{d}{dx}(  Gamma  frac{d  phi}{dx})+S=0  )

TuteeHUB · Answer

(  frac{d  phi}{dt}+  frac{d}{dx}(  Gamma  frac{d  phi}{dx})+S=0  )

TuteeHUB · Answer

(  frac{d  phi}{dt}+div(  Gamma grad  phi)+S=0  )
