# Finding points on a circle using only degrees (Sine/Cosine)!

This tutorial shows how to find a point on a circle (with any radius), using only the degree of the point. It teaches the use of Sine and Cosine in doing so. A great tutorial if you are going to be manipulating circles!

### Code

`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.`
