WebMay 1, 2024 · Defining Sine and Cosine Functions. Now that we have our unit circle labeled, we can learn how the $(x,y)$ coordinates relate to the arc length and angle.The sine function relates a real number $t$ to the $y$-coordinate of the point where the corresponding angle intercepts the unit circle. More precisely, the sine of an angle $t$ … WebSine. The sine of an angle is a trigonometric function that is denoted by sin x, where x is the angle in consideration. In a right-angled triangle, the ratio of the perpendicular and the hypotenuse is called the sine function. In other words, it is the ratio of the side opposite to the angle in consideration and the hypotenuse and its value vary as the angle varies. other name for vivitrol
