And then we want to close our brackets. And then we can do one last step of simplification here. Three, we could add the three to the 1 4th. Three is the same thing as 12 over four. 12 over four plus 1 4th is 13 4ths. So you have 13 4ths minus two cosine, two cosine of negative one. Minus e to the negative four over four.
