Unlocking The Power Of Trigonometric Identities: Simplifying Sin2X With Double Angle Identity

sin2x =

2sinxcosx

The expression sin2x can be simplified using a trigonometric identity. Specifically, the double angle identity for sine states that:

sin(2x) = 2sin(x)cos(x)

Therefore, we can rewrite sin2x as 2sin(x)cos(x). This identity can be useful in solving trigonometric equations and identities that involve sin(2x).
