tan(pi)/(8)

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

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

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

The numerical value of tan((pi)/(3))+2tan((2 pi)/(3))+4tan((4 pi)/(3))+8tan((8 pi)/(3)) is equal to (A)-5sqrt(3)(B)-(5)/(sqrt(3))(C)5sqrt(3)(D)(5)/(sqrt(3))

The value of the expression tan. (pi)/(7)+ 2 tan. (2pi)/(7)+ 4 tan . (4pi)/(7)+ 8 cot. (8pi)/(7) is equal to

The value of the expression tan. (pi)/(7)+ 2 tan. (2pi)/(7)+ 4 tan . (4pi)/(7)+ 8 cot. (8pi)/(7) is equal to

The value of the expression tan. (pi)/(7)+ 2 tan. (2pi)/(7)+ 4 tan . (4pi)/(7)+ 8 cot. (8pi)/(7) is equal to

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

Evaluate : tan frac (pi)(8) .

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