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

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

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

If tan alpha +cot alpha =a then the value of tan^(4) alpha +cot^(4) alpha=

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

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

If 0<=alpha,beta<=90^(@) and tan(alpha+beta)=3 and tan(alpha-beta)=2 then value of sin2 alpha is

tan^(2)alpha=1-p^(2) then sec alpha+tan^(3)alpha*cos ec alpha

If sin alpha=A sin(alpha+beta),Ane0 , then The value of tan alpha is

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

tan(alpha+beta)=(1)/(2),tan(alpha-beta)=(1)/(3), then find the value of tan2 alpha
