Question: Prove The Identity Tan28 Cos -cos 30 Sin 30-sino Find The Exact Value Of Sin (2cos-13) This question hasn't been answered yet Ask an expert. A similar trigonometric substitution can be used to denest (2 + ( sq root 3)), using cos 15, translating from the half angle formula of cos 30 and the difference formula of cos 45 - 30. It works for angles 150 and 75, although you get the same answer values.
