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

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+gamma=2pi then

If alpha,beta,gammain[0,pi] and alpha,beta,gamma are in AP, then (sinalpha-singamma)/(cosgamma-cosalpha) is equal to

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

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