Prove `tanx+ tany+ tanz=tan xtany tanz ` if x+y+z = `pi`

If quad y + z = pi, tan x tan y = 2 and tan x + tan y + tan z = 6 then z =

Prove that tan(x - y) + tan(y - z) + tan(z - x) = tan(x - y) *tan(y -z)* tan(z -x) .

Statement I tan5theta-tan3theta-tan2theta=tan5theta tan3theta tan2theta . Statement II x=y+z rArr tanx-tany-tanz=tan x tan y tanz

If tan^(-1) x + tan^(-1)y + tan^(-1)z= pi then x + y + z is equal to

If cos x = tan y, cos y = tan z and cos z = tan x, prove that sin x = sin y = sin z = sin18 ^ (@)

If cos x=tan y,cot y=tan z and cot z=tan x, then sin x=

If (tanx - tany)^(2) ,(tany-tanz)^(2) and (tanz-tanx)^(2) are in A.P then tanx-tany, tany-tanz, tanz-tanx are in
