`tan^(-1)(tan ((8pi)/13))=?`

Q.Find the principal value of tan^(-1)(tan9(pi)/(8))

Let tan^(-1) ( tan. (5pi)/(4))=alpha, tan^(-1) (-tan. (2pi)/(3))=beta , then

Write the principal value of tan^(-1)(tan((9 pi)/(8)))

find the principal value of tan^(-1)(tan((9 pi)/(8)))

tan^(-1){tan(-(7 pi)/(8))}

The value of tan^(-1)(tan(8*pi/6)) is

8.Find the principal value of tan^(-1)((tan(9 pi))/(8))

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

Find the value of : tan^(-1){tan(-(7pi)/8)}
