Prove that 2tan^(-1)((2)/(3))=tan^(-1)((12)/(5))

tan(cos^(-1)((3)/(5))+tan^(-1)((1)/(4)))

P.T. Cos^(-1)((4)/(5))+Sin^(-1)((3)/(sqrt34))=Tan^(-1)((27)/(11)) .

Prove that: sin^(-1)(-(4)/(5))=tan^(-1)(-(4)/(3))=co^(-1)(-(3)/(5))-pi

Prove that : cos^(-1).(4)/(5)+ tan ^(-1).(3)/(5) = tan^(-1) .(27)/(11) (ii) Prove that : sin^(-1).(3)/(5)+ tan ^(-1).(3)/(5) = tan^(-1) .(27)/(11)

show that cos^(-1)""(4)/(5)+cot^(-1)""(5)/(3)=tan ^(-1)""(27)/(11) .

Prove that : tan[cos^(-1)""((4)/(5))+tan^(-1)""((2)/(3))]=(17)/(6)
