cosθ1+cosθ2+cosθ3\large \cos \theta _{1} + \cos \theta _{2} + \cos \theta_{3} cosθ1+cosθ2+cosθ3
Given that cos(θ1−θ2)+cos(θ2−θ3)+cos(θ3−θ1)=−32\cos \left( \theta_{1} -\theta_{2} \right) + \cos \left( \theta_{2} -\theta_{3} \right) + \cos \left( \theta_{3} -\theta_{1} \right) = -\dfrac{3}{2} cos(θ1−θ2)+cos(θ2−θ3)+cos(θ3−θ1)=−23, find the value of the expression above.
