If `tan(pi/9), X` and `tan((5pi)/18)` are in `A.P.` and `tan(pi/9),y` and `tan((7pi)/18),` are also in `A.P,` then

If tan((pi)/(9)),X and tan((5 pi)/(18)) are in A.P. and tan((pi)/(9)),y and tan((7 pi)/(18)), are also in A.P,then

If tan(pi/9) , x , tan((7pi)/18) are in A.P. and tan(pi/9) , y , tan((5pi)/18) are also in A.P then find abs(x-2y)

If tan""(2pi)/(18),x andtan""(7pi)/(18) are in A.P. and tan""(2pi)/(18),t and tan""(5n)/(18) are in A.P. then the value of x/y will be

If X is A.M. of tan ((pi)/(9)) and tan((5 pi)/(18)) and y is A.M. of tan ((pi)/(9)) and tan((7 pi)/(18)), then

If x, y, z are in A.P. and tan^(-1) x, tan^(-1) y and tan^(-1)z are alos in A.P. then

If x is AM of (tan pi)/(9) and (tan(5 pi))/(18) and y is AM of tha(pi)/(9) and (tan(7 pi))/(18), then

tan x=-tan(pi/6)
