The Trig Functions sin(θ) and cos(θ) are important aspects of mathematics and science. They play a crucial role in navigation, physics, and engineering. But where do these functions come from? One way to understand their origins is through the lens of circles. By observing the movement of a point tracing around the circumference of a circle, we can see how it is connected to the creation of both the sin(θ) and cos(θ) curves. This is a fascinating concept, and one that can be explored by anyone, regardless of their math knowledge.
