Webb17 jan. 2015 · Write the complex number z = 1 + cos α + i sin α in polar form. Here is what I got so far, r = z = ( ( 1 + cos α) 2 + sin 2 α) 1 / 2. this is not pretty number but I can simplify it a little bit, but what abour a r g ( z) a r g ( z) = a r c t a n ( sin α 1 + cos α) I'm not sure if this make sense to put into the polar form. WebbExplanation: sin2α −sin4α = (cos2α −cos4α) let sin2α− sin4α = k ... Solving asin(α)− csin2(α) = bcos(α)−ccos2(α) …

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 ...
