The value of tan `alpha +2tan(2alpha)+4tan(4alpha)+...+2^(n-1)tan(2^(n-1)alpha)+2^ncot(2^nalpha)` is

The value of tanalpha+2tan(2alpha)+4tan(4alpha)+...+2^(n-1)tan(2^(n-1)alpha)+2^(n)cot(2^(n)alpha) is

If 4n alpha = pi , then the value of tanalpha*tan2alpha*tan3alpha …..tan(2n-2)alphatan(2n-1)alpha is:

Prove that: tan alpha +2tan 2alpha+ 2^(2)tan 2^(2)alpha +..... + 2^(n-1) tan 2^(n-1)alpha + 2^n cot 2^n alpha=cotalpha .

" If alpha=(2 pi)/(7) ,then the value of tan alpha tan2 alpha+tan2 alpha tan4 alpha+tan4 alpha tan alpha is "

If 4nalpha=pi , then the numerical value of tanalpha, tan2alpha,tan3alpha.....tan(2n-1)alpha is equal to
