हल कीजिए `[(x+y-a)/(x+y-b)](dy)/(dx)=(x+y+a)/(x+y+b)`

Solution of ((x+y-a)/(x+y-b))((dy)/(dx))=((x+y+a)/(x+y+b))

Solution of ((x+y-a)/(x+y-b))((dy)/(dx))=((x+y+a)/(x+y+b))

If sec((x-y)/(x+y))=a,"then "(dy)/(dx) is a) (y)/(x) b) -(y)/(x) c) (x)/(y) d) -(x)/(y)

x^(a)y^(b)=(x+y)^(a+b)provethat(dy)/(dx)=(y)/(x)

If y=xlog(x/(a+b x)),t h e nx^3(d^2y)/(dx^2)= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^2 y(dy)/(dx)-x (d) (y(dy)/(dx)-x)^2

If (x)/(x-y)=log((a)/(x-y)) then (dy)/(dx) is (a) (x)/(y), (b) 2-(x)/(y), (c) 2, (d) (x-y)/(x)

" (b) Solve: "x^(2)(dy)/(dx)=y(x+y)

If y=x log((x)/(a+bx)), thenx ^(3)(d^(2)y)/(dx^(2))= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^(2)y(dy)/(dx)-x(d)(y(dy)/(dx)-x)^(2)

Which of the following differential equations has y = x as one of its particular solution? (A) (d^2y)/(dx^2)-x^2(dy)/(dx)+x y=x (B) (d^2y)/(dx^2)+x(dy)/(dx)+x y=x (C) (d^2y)/(dx^2)-x^2(dy)/(dx)+x y=0 (D) (d^2y)/(dx^2)+x(dy)/(dx)+x y=0

x^(a)y^(b)=(x+y)^(a+b) prove that (dy)/(dx)=(y)/(x)
