WebbIf the point (3, 4) lies on the locus of the point of intersection of the lines x cos α + y sin α = a and x sin α − y cos α = b, (α is a variable), the point (a, b) lies on the line 3 x − 4 y = 0, … WebbThe answer is = cosαsnβ Explanation: ± ± n Therefore β β αsinβ ... Assume that α,β,γ ∈ [0,π/2], and sinα + sinγ = sinβ, cosβ +cosγ = cosα. Find α − β. We have sin2α +sin2β = sin α +β and os2α +cos2β = cos(α +β) So by squaring and then adding the above equations, we get (sin2α+ sin2β)2 + (cos2α +cos2β)2 = sin2 ...
