What does sine in trigonometry mean?

Answer 1

In trigonometry, sine is a fundamental function that relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse. It is commonly denoted as sin(θ), where θ is the angle in question. The sine function is also defined for all real numbers using the unit circle, where it represents the y-coordinate of a point on the circle corresponding to that angle. Sine is widely used in various applications, including physics, engineering, and signal processing.
