What is Sine?

In trigonometry, the sine of an angle in a right-angled triangle is the ratio of the length of the side that is opposite to the angle to the length of the longest side (the hypotenuse). The sine function is one of the fundamental functions in trigonometry and has wide applications in various fields such as physics, engineering, and mathematics. It is periodic and oscillates between -1 and 1. This calculator helps you find the sine value for any given angle in degrees or radians and visually represents the sine wave for better understanding.

Formula: sin(θ) = Opposite / Hypotenuse
Range: -1 ≤ sin(θ) ≤ 1
Units: Angles can be measured in degrees or radians.
