" Example "28" If "tan x=(3)/(4),pi

If tan x=(3)/(4),pi<=x<(3 pi)/(2), then tan((x)/(2)) is equal to

If tan x=(3)/(4),pi

If tan x= (3)/(4) " where " pi lt x lt (3pi)/( 2), value of tan ""(x)/(2) is

If tan""[(pi)/4 + theta ]+tan[(pi)/(4)- theta ]=a " then " tan^(3)[(pi)/(4)+ theta ] + tan^(3)[(pi)/(4)- theta]=

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

The numerical value of tan(pi/3)+2tan((2pi)/3)+4tan((4pi)/3) is equal to

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=3, then the value of tan^(2)((pi)/(4)+theta)+tan^(2)((pi)/(4)-theta)

The value of tan(pi/3)+2tan((2pi)/3)+4cot((4pi)/3)+8tan((8pi)/3) is

If tan x=3/4,pi

Let f(x)=7tan^(8)x+7tan^(6)x-3tan^(4)x-3tan^(2)x for all x in(-(pi)/(2),(pi)/(2)) . Then the correct expression(s) is (are)-
