`Now, I understand that some people may not know how to use Cosine and Sine to find the coordinates of dots on a circle, so I will explain it to the best of my ability. Here is a quick explanation. Now, you know that coordinates are shown in (X, Y), well, Cosine (Cos) finds the X and Sine (Sin) finds the Y. So really, you could think of Sine and Cosine as (Cosine, Sine). Don't get confused yet, lol, I will explain this further. Now, Cosine can be used to find the coordinates of a certain point by using the degrees of that point. Here is a quick example:`

Cosine(Point_Degree) * Radius_Length = The X coordinate of that Point. And:

Sine(Point_Degree) * Radius_Length = The Y coordinate of that Point. Here is an example of finding the (X, Y) of a point with the degree measurement of 100??, and the circle has a radius of 5. To find the X:

Cos(100) * 5,

and to find the Y:

Sin(100) * 5.

Simple enough, right? I hope this little tutorial helps you understand the use of Sine and Cosine in finding the coordinates of a point on a circle.

I've also included my CSS code to demonstrate this tutorial.
