If `"cot" theta "cot" 7 theta + "cot" theta "cot" 4 theta + "cot" 4 theta "cot" 7 theta = 1, " then" theta =`

If theta = 9^(@), then what is the value of cot theta cot 2 theta cot 3 theta cot 4 theta cot 5 theta cot 6 theta cot 7 theta cot 8 theta cot 9 theta ?

If ("cosec" theta +cot theta)=x find "cosec" theta - cot theta .

Prove that: cot theta cot2 theta + cot2 theta cot 3 theta + 2 = cot theta(cot theta - cot3 theta)

tan theta + 2 tan 2 theta + 4 tan 4 theta + 8 cot 8 theta = cot theta.

tan theta + 2 tan 2 theta + 4 tan 4 theta + 8 cot 8 theta = cot theta.

If theta=9^@ , then what is the value of cot theta cot2 theta cot3 theta cot4 theta cot5 theta cot6 theta cot7 theta cot8 theta cot9 theta ? यदि theta=9^@ ,तो cot theta cot2 theta cot3 theta cot4 theta cot5 theta cot6 theta cot7 theta cot8 theta cot9 theta का मान क्या होगा?

Prove that cot theta cot 2 theta+ cot 2 theta cot 3 theta+ 2= cot theta (cot theta- cot 3 theta) .

Show that cot theta* cot 2theta+ cot 2theta *cot 3theta + 2 = cot theta(cot theta - cot 3theta)

(cot theta + "cosec" theta -1)/( cot theta - "cosec" theta +1) is

If cosec theta - cot theta = 4, then cosec theta + cot theta =…………..
