`(x^(2)-yx^(2))dy(y^(2)+xy^(2))dx=0` को हल कीजिए।

1.	`(x^(2)-yx^(2))dy(y^(2)+xy^(2))dx=0` को हल कीजिए।
Answer» यहाँ पर `(x^(2)-yx^(2))dy(y^(2)+xy^(2))dx=0` या `x^(2)(1-y)dy+y^(2)(1+x)dx=0` या `(1-y)/(y^(2))dy+(1+x)/(x^(2))dx=0` या `int(1-y)/(y^(2))dy+int(1+x)/(x^(2))dx=c` या `int((1)/(y^(2))-(1)/(y))dy+int((1)/(x^(2))+(1)/(x))dx=c` या `-(1)/(y)-log y-(1)/(x)+logx=c` या `log((x)/(y))-(x+y)/(xy)=c`
