sine function
Circle projection onto axis
The sine function is a fundamental mathematical operation that relates an angle to the ratio of two sides in a right triangle—specifically, the opposite side divided by the hypotenuse.
In trigonometry and calculus, sine produces a smooth wave that oscillates between -1 and 1, making it essential for modeling periodic phenomena: sound waves, light, alternating current, circular motion.
The sine function describes how the pendulum's position changes over time.
Written as sin(x) or sin x.
