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).
