The equation “sin 2θ” is an expression involving the trigonometric function sine, represented by the symbol “sin,” and an angle denoted as 2θ. The “2” outside the sine function indicates that we are dealing with the double angle of θ.
The formula for sin 2θ can be derived using trigonometric identities. One of the identities states that sin 2θ = 2sinθcosθ. This identity can be proved by manipulating the sine and cosine functions using the angle addition formula.
So, if you are given an angle θ, you can find sin 2θ by first determining sinθ and cosθ. Then, multiply sinθ by cosθ, and finally multiply the result by 2. The outcome will be sin 2θ.
It is important to note that the value of sin 2θ may range from -1 to 1, as the sine function is bounded between these values for any angle input.
