Which one of the following differential equations represents the family of straight lines which are at unit distance from the origin a) (y-x(dy)/(dx))^2=1-((dy)/(dx))^2 b) (y+x(dy)/(dx))^2=1+((dy)/(dx))^2 c)(y-x(dy)/(dx))^2=1+((dy)/(dx))^2 d) (y+x(dy)/(dx))^2=1-((dy)/(dx))^2

Find degree and order xy(d^(2)y)/(dx^(2))+((dy)/(dx))^(2)-y(dy)/(dx)=2

a(x(dy)/(dx)+2y)=xy(dy)/(dx)

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

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

y^2+x^2(dy)/(dx)=x y(dy)/(dx)
