Calculate sine values in degrees and radians with unit circle visualization and trigonometric identities
The sine function is one of the fundamental trigonometric functions. In a right triangle, sine is defined as the ratio of the opposite side to the hypotenuse.
sin(θ) = opposite / hypotenuse
On the unit circle, sine represents the y-coordinate of the point where the angle intersects the circle.
