`tan^(-1)[ tan(-(3 pi)/(4))]`

Principal value of tan^(-1)[tan((3pi)/(4))] is

Principal value of tan^(-1)[tan((3pi)/4)] is

tan^(-1)(tan((5 pi)/(3)))

tan^(-1)(tan\ (3pi)/(4))

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

tan^(-1)(tan(2 pi/(3)))

If alpha=tan^(-1)(tan(5 pi)/(4)) and beta=tan^(-1)(-tan(2 pi)/(3)), then 4 alpha=3 beta(b)3 alpha=4 beta(c)alpha-beta=74 alpha=(3 beta)/(12) none of these

tan^(-1)("tan"(2pi)/3)
