Websin (-π/3) is -½√3 while cos (-π/3) has a value of ½ Already we can see that cos theta = cos -theta with this example. And look at that: sin -theta = -sin theta just like Sal said. If we go through all the other reflected angles, with this specific example of an angle, we will get the same relationships that Sal just walked us through.
