If `alpha+ beta = pi/2` and `beta + gamma=alpha`, then `tanalpha` equals

If alpha+beta=pi/2a n dbeta+gamma=alpha, then tanalpha equals

If alpha+beta=pi/2a n dbeta+gamma=alpha, then tanalpha equals 2(tanbeta+tangamma) (b) tanbeta+tangamma tanbeta+2tangamma (d) 2tanbeta+tangamma

If alpha + beta = 90^@ and beta + gamma = alpha then tanalpha-tanbeta=?

If alpha < beta < gamma and sin gamma cos alpha=1, where alpha,gamma in[pi,2 pi], then the least integral value of f(x) = | x - alpha| + | x - beta| + |x - gamma| is

If alpha , beta , gamma are the roots of the equation x^3 +px^2 + qx +r=0 then the coefficient of x in cubic equation whose roots are alpha ( beta + gamma ) , beta ( gamma + alpha) and gamma ( alpha + beta) is

If alpha + beta + gamma = pi , show that : tan (beta+gamma-alpha) + tan (gamma+alpha-beta) + tan (alpha+beta-gamma) = tan (beta+gamma-alpha) tan (gamma+alpha-beta) tan (alpha+beta-gamma)

If 2 sin alphacos beta sin gamma=sinbeta sin(alpha+gamma),then tan alpha,tan beta and gamma are in
