`tan^-1 (1/2) + tan^-1(1/3) = tan^-1(3/5) +tan^-1(1/4)`

Prove that : tan^(-1)(1/2) + tan^(-1)(1/3) = tan^(-1)(3/5) + tan^(-1)(1/4) = pi/4

Show that tan^(-1) (1/2) +tan^(-1) (1/8) = tan^(-1) (3/4) - tan^(-1)(1/18)

Prove that: tan^(-1)(1/7)+tan^(-1)(1/(13))=tan^(-1)(2/9) tan^(-1)(1/2)+tan^(-1)(1/5)+tan^(-1)(1/8)=pi/4 tan^(-1)(3/4)+tan^(-1)(3/5)-tan^(-1)(8/19)=pi/4

show that tan^(-1)(1/2)+tan^(-1)(2/11)=tan^(-1)(3/4)

Evaluate 2tan^(-1)(1/2)+tan^(-1)(1/4)

Prove that tan^-1(1/4)+ tan^-1(2/9) = 1/2sin^-1(4/5)

tan^(-1)(1/2)+tan^(-1)(1/3) is equal to
