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

Prove that cotA-tanA=2cot2A and deduce that tan alpha+2tan2alpha+4tan4alpha+8cot8alpha=cot alpha

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

tan alpha+2tan2alpha+4tan4alpha+8cot8alpha is equal to

Prove that: t a nalpha+2tan2alpha+4tan4alpha+8cot8alpha=cotalpha

Prove that: t a nalpha+2tan2alpha+4tan4alpha+8cot8alpha=cotalpha

Prove that: t a nalpha+2tan2alpha+4tan4alpha+8cot8alpha=cotalpha

Prove that: t a nalpha+2tan2alpha+4tan4alpha+8cot8alpha=cotalpha

tanalpha+2tan2alpha+4tan4alpha+8cot8alpha=?

using cotA-tanA=2cot2A deduce that tanalpha+tan2 alpha+4tan4alpha+8cot8alpha=cotalpha

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