tan8 alpha-tan5 alpha-tan3 alpha=tan8 alpha tan5 alpha tan3 alpha

Show that tan8alpha-tan5alpha-tan3alpha=tan8alphatan5alphatan3alpha

Prove that, tan 8alpha - tan 5 alpha - tan 3 alpha = tan 8alpha tan 5 alpha tan 3 alpha

" If "alpha=(2 pi)/(7)" ,and "tan alpha tan2 alpha+tan2 alpha tan4 alpha+tan4 alpha tan alpha=K" .Then "3k^(2)+4k+5=" ."

If alpha=(2 pi)/(7), then tan alpha tan2 alpha+tan2 alpha tan4 alpha+tan4 alpha tan alpha

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

If alpha=(2 pi)/(7) then tan alpha tan^(7)2 alpha+tan2 alpha tan4 alpha+tan2 alpha tan4 alpha=

If alpha = (2pi )/(7) , then tan alpha tan 2 alpha + tan 2 alpha tan 4 alpha + tan 4 alpha tan alpha =

If alpha = (2pi)/7 prove that tan alpha *tan 2alpha + tan 2alpha* tan 4alpha + tan 4alpha* tan a = - 7

tan alpha+2tan2 alpha+4tan4 alpha+8cot8 alpha=cot alpha
