WebTo get a somewhat neat expression for tan (18°) we begin by finding tan² (18°) = sin² (18°)∕cos² (18°) = (1 − cos² (18°))∕cos² (18°) = 1∕cos² (18°) − 1 = 16∕ (10 + 2√5) − 1, which can be simplified to (25 − 10√5)∕5². Again, 18° lies in the first quadrant, so tan (18°) is positive, and we get tan (18°) = √ (25 − 10√5)∕5. – – – WebDepending on which sides you have, you should choose sin, cos or tan, as shown in the diagram below. sin d = opposite side hypoteneuse side cos d = adjacent side hypoteneuse side tan d = opposite side adjacent side … ldf4-50a-42 https://camocrafting.com
