Mathematics

Can someone please explain why sin(180-theta)= sin(theta).
if you look at the sine curve you will find a vertical mirror line halfway between 0° and 180°

The two points are in phase.

If you draw both the graph of sin(180-x) and sin(x), you will see that the graph is shifted to the same position (since sine repeats every 180 degrees)
