Find the value of tan^(-1)((x)/(y))-tan^(-1)((x-y)/(x+y))

Find the value of tan^(-1)((x)/(y))-tan^(-1)((x-y)/(x+y))

Prove that tan^(-1)((x)/(y))-tan^(-1)((x-y)/(x+y)) is (pi)/(4) and Not(-3 pi)/(4)

Simplify the following: Evaluate tan^(-1)(x/y)-tan^(-1)((x-y)/(x+y))

Simplify : tan^(-1)((x)/(y))-tan^(-1)((x-y)/(x+y)).

tan ^(-1)((1)/(x+y))+tan ^(-1)((y)/(x^(2)+x y+1))=

Express the value of "tan"^(-1)(x/y)-"tan"^(-1)((x-y))/((x+y) in simplest form.

The solution of (dy)/(dx)=((x-1)^(2)+(y-2)^(2)tan^(-1)((y-2)/(x-1)))/((xy-2x-y+2)tan^(-1)((y-2)/(x-1))) is equal to

tan^(-1)x+tan^(-1)y is equal to

The solution of (dy)/(dx)=((x-1)^2+(y-2)^2tan^(- 1)((y-2)/(x-1)))/((x y-2x-y+2)tan^(- 1)((y-2)/(x-1))) is equal to
