👉 Cosine is a trigonometric function that describes the ratio of the length of an arc of a circle to its radius. It's often used in geometry and engineering, especially when dealing with circles or other curves. The cosine of an angle in radians is the ratio of the length of the side opposite the angle to the length of the hypotenuse. In mathematics, cosines are commonly denoted as c or cos(x). When working with complex numbers, cos(c) can be found using

What is the definition of Cosina? 🙋
👉 The cosine of an angle is a number that represents the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. It's denoted by cosθ or sometimes θC, and it ranges from -1 (when the angle is obtuse) to 1 (when the angle is acute).
