x sqrt(1+y)+y sqrt(1+x)=0

If x sqrt(y+1)+y sqrt(x+1)=0 & x!=y, then (dy)/(dx)=

If x sqrt (y+1) + y sqrt (x+1) =0 and x != y then dy/dx=............ A) frac{1}{(1+x)^2} B) - frac{1}{(1+x)^2} C) (1+x)^2 D) - frac{x}{x+1}

If x sqrt(1-y^(2))+y sqrt(1-x^(2))=k , then the value of (dy)/(dx) at x=0 is -

Solve the following differential equation: x sqrt(1-y^(2))dx+y sqrt(1-x)dy=0

Prove that the diagonals of the parallelogram formed by the lines sqrt(3)x+y=0, sqrt(3) y+x=0, sqrt(3) x+y=1 and sqrt(3) y+x=1 are at right angles.

Prove that the diagonals of the parallelogram formed by the lines sqrt(3)x+y=0, sqrt(3) y+x=0, sqrt(3) x+y=1 and sqrt(3) y+x=1 are at right angles.

If 2y= sqrt (x+1) + sqrt (x-1) , show that 4( x^2 -1) y2 + 4xy1 - y = 0

If 0
