Expand the Trigonometric Expression sin(2a)

Problem

sin(2*a)

Solution

1. Identify the double angle identity for the sine function.

2. Apply the formula for the sine of a double angle, which states that sin(2*θ)=2*sin(θ)*cos(θ)

3. Substitute the variable a for θ to obtain the expanded form.

Final Answer

sin(2*a)=2*sin(a)*cos(a)
