WebbSin2x Formula. Sin2x formula is one of the double angle formulas in trigonometry. Using this formula, we can find the sine of the angle whose value is doubled. We are familiar that sin is one of the primary trigonometric ratios that is defined as the ratio of the length of the opposite side (of the angle) to that of the length of the hypotenuse in a right-angled … Webb29 juli 2024 · selected Aug 9, 2024 by Dheeya.
