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

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

prove that cot theta.cot2 theta+cot2 theta*cot3 theta+2=cot theta(cot theta-cot3 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?

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 ?

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

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

(1)/(cosec theta+cot theta)=cosec theta-cot theta

If 6cot theta+2cos ec theta=cot theta+5coec theta then cos theta=

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .

tan theta+2tan2 theta+4cot4 theta=cot theta
