Trigonometric half angle formula

WebMay 31, 2024 · In trigonometry, half-angle formulas are usually represented as θ/2, where θ is the angle. The half-angle equations are used to determine the precise values of trigonometric ratios of standard angles such as 30°, 45°, and 60°. We may get the ratio values for complex angles like 22.5° (half of 45°) or 15° (half of 30°) by using the ...
