Sin 2x Formula
Sin 2x Formula is among the very few important formulas of trigonometry used to solve various problems in mathematics. It is among the various double-angle formulas used in trigonometry. This formula is used to find the sine of the angle with a double value. Sin is among the primary trigonometric ratios that are given by taking the ratio perpendicular to that of the hypotenuse in a right-angled triangle. The range of sin2x is [-1, 1].
Sine ratio is calculated by computing the ratio of the length of the opposing side of an angle divided by the length of the hypotenuse. It is denoted by the abbreviation sin. The image added below shows a right-angle triangle ABC
If θ is the angle formed between the base and hypotenuse of a right-angled triangle then,
sin θ = Perpendicular/Hypotenuse
