Cos hand trick
WebCos θ = Base/Hypotenuse. Tan θ = Perpendicular/Base. Perpendicular is the side opposite to the angle θ. The base is the adjacent side to the angle θ. The hypotenuse is the side opposite to the right angle. The other three functions i.e. cot, sec and cosec depend on tan, cos and sin respectively, such as: Cot θ = 1/tan θ. Sec θ = 1/cos θ WebDec 1, 2015 · Basically, this is due to a combination of the Niven's theorem (If q and cos(q ∘) are both rational, then cos(q ∘) equals 0, ± 1 2, or ± 1) and the fact that sin2x = 1 2(1 − cos2x). – Akiva Weinberger Dec 2, 2015 at 5:28 Show 4 more comments 34 Cosine goes horizontally (from the y-axis), sine goes vertically (from the x-axis).
