`tan^-1(tan((pi)/(4))`

Find the value of tan^(-1)(tan((3pi)/4))

Find the value of tan^(-1)(tan((3pi)/4))

cos[tan^(-1){tan((15pi)/4)}]

Write the value of tan^(-1){tan((15pi)/4)}

Evaluate each of the following: tan^(-1)(tan(9pi)/4) (ii) tan^(-1)(tan1) (iii) tan^(-1)(tan2)

Evaluate each of the following: sin^(-1)(sin(2pi)/3) (ii) cos^(-1)(cos(7pi)/6) (iii) tan^(-1)(tan(3pi)/4)

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

Let theta = tan^(-1) ( tan . (5pi)/4) " and " phi = tan^(-1) ( - tan . (2pi)/3) then

tan^(-1)((1)/(1+2))+tan^(-1)((1)/(1+6))+tan^(-1)(k)=tan^(-1)4 -(pi)/(4) then k is

Show taht 2tan^-1(tan(alpha/2)tan(pi/4-beta/2))=tan^-1((sinalphacosbeta)/(cosalpha+sinbeta))
