Trigonometry is a complex subject for most of the students but some find it interesting and fascinating. Although the geometric equations and theorems may seem complicated, but when you have the basic understanding and you find out the building blocks or foundation of a theorem, it seems not so complicated at all. Unit circle is one of the many parts that together make up trigonometry. As the name suggests; a unit circle is a circle with unit or 1 radius. In simpler words, the diameter of this circle is 2 as diameter is equal to twice the radius. You can also understand with the fact that when a line is drawn from the center of the circle to any point on the edge of the circle, the radius will be 1. The center point is what we call the origin or the point where x-axis and y-axis meet together.
The most basic purpose of using a unit circle or what we commonly refer to as trigonometry circle is that it allows us to calculate the tangent, cosine and sine of any angle that stays in between 0 degree to 360 degrees. If you draw a horizontal line that is also known as cosine to the edge of the circle and then draw a vertical line from the origin as well and it will be known as sine. These two lines will form a triangle with a specific angle and you can solve this triangle using Pythagorean Theorem that states that 2 sides of a triangle are equal to the length of the third side.

Uses and Market Practices of Unit Circle Charts:
There are great chances that even if you learnt trigonometry in high school or college, you don’t use it at job. There are only a few jobs and fields that actually use the application of trigonometry equations i.e. Pythagorean Theorem or unit circle charts. Learning about all of these equations and theorems may seem useless now that you are working as a marketing executive, but keep in mind that trigonometry will surprise you with the fact that it’s used more often that you might consider. You just need to look around you and chances that you will find a person using some form of trigonometry at their job. From calculating the height of a building to designing a video game to calculating the travel time from one point to another are some of the many applications of unit circles.
It’s actually amazing to see how often a unit circle is used in real life and if you dig deeper to find out, you will be amazed to see that from locating a submarine’s location underwater to finding out the real time position of an incoming missile in the air so it can be destroyed before approaching the target, there are hundreds of day to day uses of unit circles that are applied right in front of your eyes and just need to look out for these. Did you notice that when someone cuts a pizza into slices, he is actually using unit circle to start the cutting from one edge and moving the cutter right from the origin or the through the point where x-axis and y-axis meet? Unit circles have this much common applications in regular life.
