2tan^(-1)(1)/(3)=tan^(-1)(3)/(4)

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

Prove that 2tan^(-1)((1)/(2))=tan^(-1)((4)/(3))

Prove that 3tan^(-1)((1)/(2+sqrt(3)))-tan^(-1)((1)/(2))=tan^(-1)((1)/(3))

Prove the following: 2\ tan^(-1)3/4-tan^(-1)(17)/(31)=tan^(-1)pi/4

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

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

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

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

tan^(-1)((1)/(2))+tan^(-1)((1)/(3))=(pi)/(4)|0tan(1)+tan(1)
