[" The value of "],[tan^(-1)((m)/(n))-cot^(-1)((m+n)/(m-n))" is "]

The value of ["tan"^(-1)(m)/(n)-tan^(-1)((m-n)/(m+n))] is -

What is the value of tan^(-1)((m)/(n))-tan^(-1)((m-n)/(m+n))?

What is the value of tan^(-1)((m)/(n))-tan^(-1)((m-n)/(m+n)) ?

Tan^(-1)(m/n)-Tan^(-1)((m-n)/(m+n))=

tan^(-1)(m/n)+tan^(-1)((n-m)/(n+m))=?

Prove that tan^(-1)((m)/(n))-tan^(-1)((m-n)/(m+n))=(pi)/(4).

" The value of "cot^(-1)((1+2^(2))/(3))+cot^(1)((1+6^(2))/(5))+cot^(-1)((1+12^(2))/(7))+..." up to "8" terms is "tan^(-1)((m)/(n))" .(where "m,n" are coprime ) then "m+n" is equal to "

Prove that: tan^(-1)(m/n)+tan^(-1)((n-m)/(n+m))=pi/4
