WebThe sum differene identity can also be used to find the exact value of normal trig functions. For example if told to find the exact value of sin75 degrees you can use the formula for … WebSolution to Example 2. Use the difference formula (formula 2 above) for cosine to expand the given expression. cos (x - π/2) = cos x cos π/2 + sin x sin π/2. cos π/2 = 0 and sin π/2 = 1, hence. cos (x - π/2) = sin x. Example 3. Find the exact value of sin (15°) Solution to Example 3. 15 ° is not a special angle.
