Could anybody please help me in solving the following PDF equation? (p + r/rou)*(1- (Derivative[1, 0][f][x, t])^2 - k * Derivative[0, 1][f][x, t])/Sqrt[1 + (Derivative[1, 0][f][x, t])^2] ==0 with initial or boundary conditions as f[x, 0] == -1 Derivative[0, 1][f][x, 0] == p/k Derivative[1, 0][f][R0, t] == 0 f[x, t] == If[0<= x <=1, Sqrt[1 - x^2]] where, p, k, R0 and rou are constants. Thanks in advance. Wei
