Webb5 Answers. sin 2 θ 2 + cos 2 θ 2 = 1. ( 3 5) 2 + cos 2 θ 2 = 1. Given that, you can find that cos θ 2 = ± something. Once you've got sin θ 2 and cos θ 2, use the fact that sin θ = 2 sin θ 2 cos θ 2 and cos θ = cos 2 θ 2 − sin 2 θ 2 (double-angle formulas). Then there's still a … Webbθ; x=v 0x.2t= 2 θ θ 2v sin cos0 g =2h.cot θ yazabiliriz. Buradan 0 2v sin cos2 θ θ g =2 θ 2 g v cos0 2 g cot θ; tan 2θ=2; tan θ= 2; θ≈55 ° olarak bulunur. 2.
