The formula for sin(2θ) is:
sin(2θ) = 2 sin(θ) cos(θ)
This can be derived using the trigonometric identity for the sine of the double angle:
sin(2θ) = 2 sin(θ) cos(θ)
Where:
θ represents the angle in radians or degrees.
sin(θ) is the sine of the angle θ.
cos(θ) is the cosine of the angle θ.
So the full formula for sin(2θ) is 2 times the product of the sine and cosine of the angle θ.
