If `cot^2 theta = cot (theta-alpha) cot (theta-beta)`, then show that `cot 2theta =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

If cos ec theta-cot theta=alpha, then cot theta is

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

Prove that : cot theta-tan theta=2cot2 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?

Find cot^2 theta - cot^2 alpha . .

Solve: cot5theta=cot2theta

Solve: cot5theta=cot2theta

Prove that, cot theta - tan theta = 2cot 2 theta
