The answer choice which sin(x + y) - sin(x - y) simplifies to is; 2(cos x)(sin y).
<h3>
Which of the following expressions does sin(x + y) - sin(x - y) simplify to?</h3>
It follows from the task content that the expression given in the task content can be simplified by trigonometric identities as follows;
sin(x + y) - sin(x - y) = sinxcosy + cosxsiny - (sinxcosy -cosxsiny)
= 2cosxsiny.
