cot A+cot(60^(@)+A)-cot(60^(@)-A)=3cot3A

Prove the following identity: cot A+cot(60^(@)+A)+cot(120^(@)+A)=3cot3A

Prove that: cotA+"cot"(60^0+A)-cot(60^0-A)=3cot3A

Prove that: cotA+"cot"(60^0+A)-cot(60^0-A)=3cot3A

Prove the following identity: cot A+cot(60^0+A)+cot(120^0+A)=3cot3A

cot A + cot (60^(@) + A) + cot (120^(@) +A) = 3 cot 3 A.

"Prove that " cotA + cot ( 60^(@) + A) + cot (120^(@) + A) = 3 cot 3 A.

Given that: A = cot 30^(@) and B = (cot60^(@) cot30^(@) +1)/(cot30^(@) - cot 60^(@)) , which of the relations stated below is true ?

Show that: (cot 30^(@) cot 60^(@) - 1)/(cot 30^(@) + cot 60^(@)) = cot 90^(@)

The value of cot x+cot(60^(@)+x)+cot(120^(@)+x) is equal to

Value of (3 + cot 80^(@) cot 20^(@))/( cot 80^(@) cot 20 ^(@))
