Web25 Nov 2014 · tan θ = 2 tan θ 2 1 − tan 2 θ 2 = 2 t 1 − t 2. Similarly (1) sin θ = 2 sin θ 2 cos θ 2. If t = tan θ 2 = opp adj = opp 1 so the opposite side is t and the adjacent side is 1, then the hypotenuse is 1 + t 2 so sin θ 2 = t 1 + t 2 and cos 2 = 1 1 + t 2 so ( 1) becomes 2 t 1 + t 2. A similar thing handles the cosine. Web\theta=tan^{-1}\left(\frac{\frac{3}{5}}{-\frac{1}{4}}\right) he. image/svg+xml. פוסטים קשורים בבלוג של Symbolab. Practice, practice, practice.
