About this calculator
The sine of an angle is the ratio of the length of the side opposite that angle to the hypotenuse in a right triangle, or equivalently the y-coordinate of a point on the unit circle at that angle. This calculator accepts the angle in either degrees or radians and converts internally (radians = degrees × π/180) before evaluating, since most math libraries and calculators compute sine in radians natively.
It's a foundational operation in trigonometry homework, but also in real engineering: sine drives the vertical component of projectile motion, the voltage waveform of AC electricity, sound wave synthesis, and the rotation matrices used in computer graphics and robotics.
