Hi,

when i tried to solve the following equation, i received ""Warning, solutions may have been lost"":

i'm using maple 15 and trying to solve the following PDE without success, can you help please.

(ab+(a*sin(x1))^2-(c*cos(x1))^2)*d/dx1(V(x1,x2))=-dsin(x1)/exp(x1).

where a,b,c and d are constants. and i need it to be solved as a PDE please.

thank you,

Mutaz

Hi,

can anyone help me in solving the following PDE:

restart:

with(PDEtools):

> PDE := M1(x1, x2)*(diff(M1(x1, x2), x1))+(diff(M1(x1, x2), x2))*M2(x1, x2)*(1+x1^2)-2*x1*M2(x1, x2) = 0;

thank you,

regards,

Mutaz
