Jan 18, 2024 · To calculate the sin 2 theta, use the double angle formula, a particular case of the compound angle formula. Start with the compound angle formula: sin(α + ß) = sin(α)cos(ß) + sin(ß)cos(α). Substitute the angle ß with α: sin(α + α) = sin(2α) = 2sin(α)cos(α). The result is the double angle identity for the sine.
