Hello machnla,

(∂f(x,y))/∂x=Axy+Bx^2
(∂f(x,y))/∂y=Cy^2+Dxy^2
f(x,y) hoyanne kohomada?

Hello machnla,

(∂f(x,y))/∂x=Axy+Bx^2........(1)
(∂f(x,y))/∂y=Cy^2+Dxy^2.....(2)
f(x,y) hoyanne kohomada?

(∂f(x,y))/∂x=Axy+Bx^2;
Meka Anukalanaya karanawa x wishayen....Partial defferentiate karaddi aneth variable eka ganan ganne ne wage...Aneth paththata y ganan nogena Anukalanaya karanawa.......

f(x,y)=Ayx^2/2+Bx^3/3+f

Habai Abimatha niyathaya y matha rada pawathinawa...Eka niyathaknewei..Ei f(x,y),x,y wala function ekakne....(nikan function ekak anukalanaya karama dana niyathe variable eka matha rada pawathinne ne wage thama....)

(∂f(x,y))/∂y=Ax^2/2+f '....(3)
f kiyanne y wala function ekakne..eka y walin awakalanaya karama...f '..

Dan meka (2) ta samana karanawa....
Ax^2/2+f '=Cy^2+Dxy^2
f '=Cy^2+Dxy^2-Ax^2/2
Meka onama x,y walata true wenne....
A=0,.....(4)

(f ' only depend on y not x)

f '=Cy^2...

Dan meka normal differential equation ekak...Anukalaya karanta thiyenne...
f=Cy^3/3+k

(4)n,

f(x,y)=Bx^3/3+Cy^3/3+k.....where k is a constant independent of x,y
