sin2theta
Sin2θ, often written as sin(2θ), denotes the sine of the angle obtained by doubling θ. In trigonometry, it is a standard double-angle expression used to simplify and manipulate trigonometric expressions.
The most common form is the double-angle formula sin 2θ = 2 sin θ cos θ. This follows from
Key properties include its range and period. Since it is a sine function of 2θ, its values
Applications of sin 2θ appear across mathematics and physics. It is used to simplify products of sine
