Hi, Oli,
what's wrong with this function? Can you calculate derivatives? The derivative from this function 
is typically calculated in mind, e.g. without going to paper-pencil tools, let along Mathematica.

Ok, check Mathematica Help/D, if you cannot.

Have success, Alexei

how can one find the maxima by using mathematica for the following function:

f[x_] := 1/(8*(Pi*t)^(3/2)) * Exp[(-(x^2 + y^2 + z^2)/4*t)]

i mean, the first derivation equal Zero.
Thanks in advance..
