So this is 2 times cosine of 0, which is 1. So it's 2 minus 2 cosine of 2 times 0. Cosine of, let me write it this way. Actually, let me just do it this way. If we just straight up evaluate the limit of the numerator and denominator, what are we going to get? We're going to get 2 cosine of 0, which is 2, minus 2 times cosine of, well, this 2 times 0 is still going to be 0. So minus 2 times cosine of 0, which is 2.
