Statement I tan alpha+2tan 2 alpha+4 tan 4 alpha + 8 tan 8 alpha+16 cot 16 alpha=cot alpha Statement II cot alpha- tan alpha=2 cot 2 alpha

Which of the following identities,wherever defined,hold(s) good? (a) cot alpha-tan alpha=2cot2 alpha(b)tan(45^(@)+alpha)-tan(45^(@)-alpha)=2cos ec2 alpha(c)tan(45^(@)+alpha)+tan(45^(0)-alpha)=2sec2 alpha(d)tan alpha+cot alpha=2tan2 alpha

Prove that cot alpha - tan alpha =2 cot 2 alpha.

(1)/(tan3 alpha-tan alpha)-(1)/(cot3 alpha-cot alpha)=cot2 alpha

The number of solutions of the equation tan^(2)alpha-cos es^(2)alpha+4cot^(2)2 alpha+4tan alpha cot2 alpha=0in(0,(pi)/(2))-{(pi)/(4)} is

If quad cot^(-1)sqrt(tan alpha)-tan^(-1)sqrt(tan alpha), then tan ((pi)/(4),(u)/(2))i sequa<0 (a) sqrt(tan alpha)(b)sqrt(cot alpha)(c)tan alpha(d)cot alpha

1/(tan3alpha-tanalpha)-1/(cot3alpha-cotalpha)=cot2alpha

tan alpha+2tan2 alpha+4tan4 alpha+8tan8 alpha+16tan16 alpha+32cot32 alpha. is equal to: (1)cot alpha(2)tan alpha.(3)cos alpha(4)sin alpha
