Trigonometry can feel like quite an abstract subject. Arcane terms like "sin" and "cos" just don't seem to correspond to anything in reality, and it's hard to get a grasp on them as concepts. The unit circle helps substantially with this, offering a straightforward explanation of what the...
The unit circle is a circle with a radius of one unit.The unit circle is fundamentally related to the concepts of trigonometry. The trigonometric functions can be defined using the unit circle.A unit circle on the Cartesian plane is shown below. It has its center at origin and all the ...
Trigonometry has also expanded to include a vast number of physical phenomena including sound waves, light rays, pendulums, and orbits of atomic particles. A study of trigonometry will primarily involve concepts of angles, the right triangle, and the unit circle. ...
