If f (θ) = acos (α + θ) + bcos (β + θ) where a, b, α and β are known quantities then –. If α,β ∈ (0, ) and α + β = σ (constant) then the maximum values of the expression ... WebWe can use the product-to-sum formulas, which express products of trigonometric functions as sums. Let’s investigate the cosine identity first and then the sine identity. Expressing Products as Sums for Cosine. We can derive the product-to-sum formula from the sum and difference identities for cosine. If we add the two equations, we get:
