`cot(45+theta)cot(45-theta)=`

The value of cot(180+theta)cot(90-theta) is:

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?

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

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 ?

(cot2 theta-cot3 theta)/(cot theta) is equal to

If cot^(2)theta=cot(theta-alpha)cot(theta-beta), then show that cot2 theta=(1)/(2)[cot alpha+cot beta]

If cot^(2) theta= cot (theta-alpha) cot( theta- beta) , prove that cot alpha+ cot beta=2 cot 2 theta

Prove that: cot theta+cot(60^(@)+theta)+cot(120^(@)+theta)=3cot3 theta
