1.`y(1-xy)dx-x(1+xy)dy=0`

(1-x^2)(1-y)dx=x y(1+y)dy y 4. (1 - x?) (1 - y) dx = xy (1 + y) dy

(3xy+y^(2))dx+(x^(2)+xy)dy=0

Find the particular solutions of : (1+xy)y dx + (1-xy)x dy = 0, y(1)=1 .

y(xy+1)dx+x(1+xy+x^(2)y^(2))dy=0

Find the particular solution of the differential equation (3xy+y^(2))dx+(x^(2)=xy)dy=0;f or x=1,y=1

Equation of curve passing through (1,1) & satisfyng the differential equation (xy^(2)+y^(2)+x^(2)y+2xy)dx+(2xy+x^(2))dy=0 is

(1+x)(1-y)(dy)/(dx)+xy=0

(1-x^(2))(dy)/(dx)-xy=1

((dy)/(dx))^(2)-(x+y)(dy)/(dx)+xy=0

solve sqrt(1+x^(2)+y^(2)+xy)+xy(dy)/(dx)=0
