Web1.5 sin θ = cos θ. Squaring both sides we have. 2.25 sin 2 θ = cos 2 θ. and since cos 2 θ = 1 − sin 2 θ we have. 2.25 sin 2 θ = 1 − sin 2 θ 2.25 sin 2 θ + sin 2 θ = 1 3.25 sin 2 θ = 1. From this, you can figure out the value of sin 2 θ. Taking square roots will tell you something about the absolute value of sin θ. WebThe Lesson The cosine function relates a given angle to the adjacent side and hypotenuse of a right triangle.The angle (labelled θ) is given by the formula below: In this formula, θ is an angle of a right triangle, the adjacent is the length of the side next to the angle and the hypotenuse is the length of longest side. cos −1 is the inverse cosine function (see Note).
