If `3tan4 alpha-10tan^2alpha+3=0` then principal values of '`alpha`' are

" If "3tan^(4)alpha-10tan^(2)alpha+3=0" then principal values of "'alpha'" are "

Solve 3tan^(4)alpha-10tan^(2)alpha+3=0

If 0 lt alpha lt (pi)/(16) and (1+tan alpha)(1+tan4alpha)=2 , then the value of alpha is equal to

If 0 lt alpha lt (pi)/(16) and (1+tan alpha)(1+tan4alpha)=2 , then the value of alpha is equal to

If 4 n alpha = pi , then the numerical value of tan alpha tan 2 alpha tan 3 alpha….tan (2n - 1) alpha is equal to

If tan alpha= sqrt2-1 then the value of tan alpha-cot alpha = ?

If tan alpha = sqrt3+2 , then the value of tan alpha - cot alpha is

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