Webb27 mars 2024 · Given sinα = 12 13, where α is in Quadrant II, and sinβ = 3 5, where β is in Quadrant I, find the exact value of sin(α + β). To find the exact value of sin(α + β), here we use sin(α + β) = sinαcosβ + cosαsinβ. The values of sinα and sinβ are known, however the values of cosα and cosβ need to be found. Webb23 mars 2024 · Write the following difference of sines expression as a product: sin(4θ) − sin(2θ). Solution We begin by writing the formula for the difference of sines. sinα − sinβ = 2sin(α − β 2)cos(α + β 2) Substitute the values into the formula, and simplify. sin(4θ) − sin(2θ) = 2sin(4θ − 2θ 2)cos(4θ + 2θ 2) = 2sin(2θ 2)cos(6θ 2) = 2sinθcos(3θ) Exercise …
