what's your question , sailor?

okay: i need to use derivative to verify that : p(x,t) = (1/(Sqrt[4 Pi t])) Exp[ -x^2/(4 t) is the solution of the diffusion equation dp/dt= d^2p/dx^2

Looking for something else?

i got the value for dp/dt with the function :pt = D[(1./(Sqrt[4 Pi t])) Exp[ -x^2/(4 t)], t]

but my second derivative of dx gives me 0.

dx = D[(1./(Sqrt[4 Pi t])) Exp[ -x^2/(4 t)], {x, 2}] is there soemthign wrong with my equation?

:(

  • anonymous
so are you trying to solve differential equation or take second derivative?
anonymous
  • anonymous
second derviative goes like this D[ Type function here ,{x,2}]
anonymous
  • anonymous
ya thats what i did
anonymous
  • anonymous
D[(1./(Sqrt[4 Pi t])) * Exp[ -x^2/(4 t)], {x, 2}]

./ i was just trying to make the whole thing into a number so i tried to multiple (dividde) by 1. lol
