Webb2) Replace all trigonometric functions with just \sin \theta sinθ and \cos \theta cosθ where possible. 3) Identify algebraic operations like factoring, expanding, distributive property, adding and multiplying fractions. This allows us to simplify the expression further. 4) Use the various trigonometric identities. Webbsin (-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.
