This is a normal post I loved it until I got to the Integration/Differentiation part
-F(x,y,z,t-2h)+16*F(x,y,z,t-h)-30*F(x,y,z,t)+16*F(x,y,z,t+h)-F(x,y,z,t+2h)
Ftt = ¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾
12h²

Fx(x,y-2h,z,t)-8*Fx(x,y-h,z,t)+8*Fx(x,y+h,z,t)-Fx(x,y+2h,z,t)
Fxy = ¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾¾
12h

etc..

"From these, it’s easy to generalize to any number of independent variables."
