The value of ("sin"^(-1)(4)/(5)+2"tan"^(-1)(1)/(3)) is -

What is the value of sin^(-1)""(4)/(5)+2tan^(-1)""(1)/(3) ?

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)

sin(2tan^(-1) .(4)/(5))= ?
