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( (pi)/9),x, tan ((5pi)/18) are in A.P. and tan(pi/9), y,tan ((7pi)/18) are also in A.P. then find the relation between x and y

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

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

Given that tan""(pi)/(9),x,tan""(5pi)/(18) are in A.P. Also given that tan""(pi)/(9),y,tan""(7pi)/(18) are in A.P. Then we have

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