The numbers tan (-(11pi)/(6)), tan((21pi)/(4))and cot ((283pi)/(6)) are in-

tan x=-tan(pi/6)

Roots of the equation are (z+1)^(5)=(z-1)^(5) are (a)+-i tan((pi)/(5)),+-i tan((2 pi)/(5))(b)+-i cot((pi)/(5)),+-i cot((2 pi)/(5))(c)+-i cot((pi)/(5)),+-i tan((2 pi)/(5))(d)none of these

Find the value tan((pi)/(5))+2tan((2 pi)/(5))+4cot((4 pi)/(5))

cos ((5pi)/(4)) - sin ((5pi)/(4)) + tan((11pi)/(4)) - cot((11pi)/(4))=

(sec2x-tan2x) equals a tan(x-(pi)/(4))b)tan((pi)/(4)-x)c cot(x-(pi)/(4))d tan^(2)(x+(pi)/(4))

sin((7 pi)/(4))*cos((7 pi)/(6))*tan((3 pi)/(4))*cot((11 pi)/(6)) is equal to

Prove that tan((pi)/(12))+tan((pi)/(6))+tan((pi)/(12))tan((pi)/(6))=1
