[最も選択された] cos theta =-√3/2 321450-If cos theta=-2/3 which of the following are possible
Trigonometric Functions are formed when trigonometric ratios are studied in terms of radian measure for any angle (0, 30, 90, 180, 270)These are also defined in terms of sine and cosine functions In this article, we will provide you with all the details on trigonometric functions such as value in degree, radians, complete trigonometric table and other relevant information cos 3¶ =√3/2 we know that cos 30° =√3/2 Ur Wlcm This discussion on If 2cos 3theta =under root 3 ,then find the value of theta ? By using the value of cosine function relations, we can easily find the value of sin 1 degrees Using the trigonometry formula, sin (90 a) = cos a, we can find the sin 1 value We know that the value of cos 30 degrees is √3/2 Therefore, sin 1° = √3/2
