Actually the whole movie was unscripted, they just put all the actors into an arena and filmed it, then brought the dead ones back to life and forced them all to say that it was just a movie
The sin of an angle in a right triangle is the ratio of the opposite side over the hypotenuse. Tan happens to be the ratio of the opposite over the adjacent side. It so happens that tan is also the ratio of the opposite over the hypotenuse and the opposite over the adjacent. So dawg, you put the sin over the tan, which makes the sin really be over the sin over the cosine(adjacent over hypotenuse), which really do be the cosine. I don't quite understand what role Morgan Freeman plays into this but I'll leave that part to jokexplain.
Posting this because I simply hate anything that has something to do with pre-written laws,formulas, so I'm surprised I managed to get this one whitout thinking. but this one is kinda good. also, puddin.
