If `alpha + beta +gamma=pi/2` and `Cot alpha, Cotbeta, Cotgamma` are in `A.P .` then `Cot alpha .Cotgamma`

If alpha + beta + gamma = π/2 and cot alpha, cot beta, cot gamma are in Ap. Then cot alpha. Cot gamma

If alpha+beta+gamma=(pi)/(2) and cot alpha,cot beta,cot gamma are in A.P. then cot alpha.cot gamma

If alpha + beta + lambda = (pi)/(2) and cot alpha, cot beta, cot lambda are in A.P then cot alpha. Cot lambda

If alpha , beta , gamma in [0,pi] and if alpha , beta , gamma are in A.P then ( sin alpha - sin gamma)/( cos gamma -cos alpha) is equal to

If alpha, beta, gamma in [0, pi]"and if" alpha, beta, gamma are in AP, then (sin alpha - sin gamma)/(cos gamma - cos alpha) is equal to

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

If alpha,beta,gammain[0,pi] and alpha,beta,gamma are in AP, then (sinalpha-singamma)/(cosgamma-cosalpha) is equal to ............... A) sin beta B) cos beta C) cot beta D) 2 cos beta

If alpha+beta=(pi)/(2) and beta+gamma=alpha, then tan alpha equals
