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 ?

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