WebJun 26, 2015 · There is only one part of the proof that will change if we decide to use degrees as opposed to radians and that is when we find the area of the sector subtended by θ. When we use radians we get: AAB = π12 ∗ θ 2π = θ 2 --just as they found in the given proof. If however, we use degrees then we will get: AAB = θ ∗ π 360. WebAug 17, 2001 · 2.

WebSolution 1: As we saw above, \cos\theta=0 cosθ = 0 corresponds to points on the unit circle whose x x -coordinate is 0 0. Since these points occur at the points of intersection with the y y -axis, the possible values of \sin \theta sinθ are the possible y y -coordinates, which are 1 1 and -1 −1. _\square . Solution 2: brother accept aftermarket tonerThere are several equivalent ways for defining trigonometric functions, and the proof of the trigonometric identities between them depend on the chosen definition. The oldest and somehow the most elementary definition is based on the geometry of right triangles. The proofs given in this article use this definition, and thus apply to non-negative angles not greater than a right angle. For greater and negative angles, see Trigonometric functions. brother accesorios
