Webcos² (φ/2) = (cos (φ) + 1)/2. or. cos (φ/2) = ±√ ( (cos (φ) + 1)/2) Which is the result we wanted. Now once you have that, you can get the sine case by substituting for sin (φ/2) …
WebFeb 12, 2024 · The cosine of an angle of a right triangle is defined as the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The given … WebFrom the unit circle definition, the coordinates of the point M are (cosθ, sinθ). And so, ¯ OC is cosθ and ¯ OS is sinθ. Therefore, OM = √ ¯ OC2 + ¯ OS2 = √cos2θ + sin2θ. Since M lies in the unit circle, OM is the radius of that circle, and by definition, this radius is equal to 1.
