Get sin from cos
Did you know?
WebRecall that tan α = sin α cos α. Now your equation states that sin α = 1 2 cos α. Squaring both sides gives sin 2 α = 1 4 cos 2 α = 1 4 ( 1 − sin 2 α). Or sin 2 α = 1 5. Similarly one … Webd) To show that a/θ = (1/3)a^3sin(θ)[3cos(θ) - 1], we can start with the expression for V from part (b): V = (1/6)πa^3 (sin(θ) - sin^3(θ)) Differentiating V with respect to θ, we get: …
