WebDeriving the double-angle formula for sine begins with the sum formula, (7.3.1) sin ( α + β) = sin α cos β + cos α sin β. If we let α = β = θ, then we have. sin ( θ + θ) = sin θ cos θ + cos θ sin θ sin ( 2 θ) = 2 sin θ cos θ. Deriving the double-angle for cosine gives us three options. First, starting from the sum formula, cos ... Webin the literature is called Kron-reduction [5]. This Kron-reduction uses the Schur-complement to reduce the number of agents in the system. It turns out that also this reduction technique is a candidate for a ’good’ reduction. Now that we have found two appropriate reduction techniques we have to analyze if the reduced systems are a good ...
