(sqrt(x+y))/(x-y)

If x is very large as compare to y, then prove that sqrt((x)/(x+y))*sqrt((x)/(x-y))=1+(y^(2))/(2x^(2))

if x is very large as compare to y,then the value of k in sqrt((x)/(x+y))sqrt((x)/(x-y))=1+(y^(2))/(kx^(2))

If x is very large as compare to y,then the value of kin sqrt((x)/(x+y))sqrt((x)/(x-y))=1+(y^(2))/(kx^(2))

If sqrt(x+y)(x-2y)^(2)=2," then "((dy)/(dx))" at "(3,1) is

The value of f(x,y)=((4sqrt(x^(3)y)-4sqrt(x^(3)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/(4sqrt(xy)))^(-2)(1+2sqrt((y)/(x))+(y)/(x))^((1)/(2)) when x=9,y=0.04

The area bounded by the line x=1 and the curve sqrt((y)/(x))+sqrt((x)/(y))=4 is

Solution of the differential equation (y+x sqrt(xy)(x+y))dx+(y sqrt(xy)(x+y)-x)dy=0 is

Evaluate (sqrt(x)+sqrt(y))(sqrt(x)-sqrt(y))

(sqrt(x)-sqrt(y))(sqrt(x)+sqrt(y)) = ……………..
