3. `(1+x^(2))tan^(-1)x(dy)/(dx)+y=0`

Solve the equation: (1+x^2)tan^-1x*(dy)/(dx)+y=0

y=(x^(2)+1)tan^(-l)x find (dy)/(dx)

Solve the differential equation: (i) (1+y^(2))+(x-e^( tan ^(-1)y))(dy)/(dx)=0 (ii) x(dy)/(dx)+cos^(2)y=tan y(dy)/(dx)

If log (x^(2)+y^(2))=tan^(-1)((y)/(x)), then show that (dy)/(dx)=(x+y)/(x-y)

If y=log{((1+x)/(1-x))^(1//4)}-(1)/(2)tan^(-1)x," then "(dy)/(dx)=

The solution of differential equation (1+y^(2))+(x-e^(tan^(-1)y))(dy)/(dx)=0 , is

If y=tan ^(-1) ((a-x) /(1+x^(2))),then (dy)/(dx) =

If y=x^(tan ^(-1)x) ,then (dy)/(dx)=
