Understanding Sine

Sine is a fundamental trigonometric function that describes the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right-angled triangle. In a unit circle, for an angle θ, sine(θ) represents the y-coordinate of the point on the circle.

Angles can be measured in degrees or radians. Degrees are a common unit where a full circle is 360°. Radians are based on the radius of a circle, where a full circle is 2π radians. This tool allows you to calculate sine for angles in both units.

Sine function is widely used in physics, engineering, and mathematics to model periodic phenomena such as waves and oscillations. For example, in wave mechanics, sine waves are used to describe the motion of simple harmonic oscillators, and in electrical engineering, they are used to represent alternating currents.
