`int (tanphi+tan^3phi)/(1+tan^3phi) dphi`

The equation tan^(2)phi+tan^(6)phi=tan^(3)phi*sec^(2)phi is

Prove that (tan phi)/(1-cot phi)+(cot phi)/(1-tan phi)=1+tan phi+cot phi

If : sin (theta + phi) = 2 sin (theta - phi), "then" : tan theta = A) tan phi B) 2 tan phi C) 3 tan phi D) 4 tan phi

The value of (sec phi(1-sin phi)(sin phi+cos phi) (sec phi+tan phi))/(sin phi(1+tan phi)+cos phi(1+ cot phi)) is equal to :

(tan^(2)phi)/(1+tan^(2)phi)+(cosec ^(2)phi)/(sec^(2)phi+cosec^(2)phi)=1

If tan theta = cos2 alpha tan phi, prove that tan (phi - theta) = (tan^(2) alpha sin 2 phi)/(1+ tan^(2) alpha cos 2 phi)

If tan (theta/2)=tan^3 (phi/2) and tanphi=2tanalpha ,then prove that theta+phi=2alpha

If 3 tan theta tan phi=1, then (cos (theta-phi))/(cos (theta+phi)) is

If 3 tan theta tan phi=1, then (cos (theta-phi))/(cos (theta+phi)) is

If 3 tan theta tan phi=1, then (cos (theta-phi))/(cos (theta+phi)) is
