If `cot^(3)alpha+cot^(2)alpha+cot alpha=1` then which of the following is/are correct :

If cot^3alpha +cot ^2 alpha + cot alpha =1 then

If tan alpha+cot alpha=2 then

Sum of three positive numbers alpha,beta and gamma is (pi)/(2). if cot alpha+cot gamma=2cot beta, then which of the following hold(s) good(A)cot alpha*cot gamma=3 (B) cot alpha*cot gamma=2(C)sum cot alpha=prod cot alpha (D) sum tan alpha=prod tan alpha

if cot^(-1)alpha+cot^(-1)beta=cot^(-1)x then x

cot alpha+cot(60+alpha)-cot(60-alpha)=3cot3 alpha

If: cot^(-1)alpha + cot^(-1)beta = cot^(-1) x , then: x=

If alpha + beta = 90^@ and cot alpha = 4/3 then cot beta =

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

if cot^-1alpha+cot^-1beta=cot^-1x then x

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