Angular velocity is equal to the circumference pi r) times the frequency; if whirling a mass around in a horizontal circle, can find the radius of the circle by (length of string x sinangle), then use the above equation
In pre-calculus, the unit circle is sort of like unit streets, it’s the very small circle on a graph that encompasses the coordinates. It has a radius of hence the unit. The figure here shows all the measurements of the unit circle:

About the Golden Ratio: The Golden Ratio can be illustrated within special dimensions of Sprials, Triangles and Rectangles where the ratio of the length of the short side to the long side is was noted by ancient Greek architects as the most visually
This equation computes the force of friction (`F_f`)on an object which is stationary on an inclined plane. This equation defines the minimal force of friction required to keep the object in a static location on an inclined plane.
