PASSION FOREVER

As the humans advanced through times, our technology started to become far more complex and there as a need for a standardized set of units for the whole world to follow. A set of unit that is universal and anyone in the world using those standard would be able to achieve the same results. In the early of times the unit of length was based on human bodies. For example the Egyptians used cubits as the measurement of length, a cubit is about 52 centimetres or about the size of a human forearms. In the United Kingdoms, the British imperial system standard measurement for anything was set by the ruler of time, for example a foot would be how far the king would move in one step, or the size of their feet or arm. The fault seems to be very clear in this technique, with every different ruler the measurement system would change and there would be no standardization. Therefore, there arrived some set of unit which were readily accepted by the technological world and are being followed to this d...

  There is a very simple relation to calculate the length of an arc, but to understand the relation we have to first know where it comes from. Arc is a portion of circumference or the curved path with a constant radius stretching from point A to point B. Arc length is the measure of the length of this arc. Arc have a central point around which it is curved, it is the center of the circle that would be formed if the arc is given a full 360o rotation. The other characteristic it has is the angle between the started and ending points if a line was stretched between the end points of arc and the center point, then the angle between these two lines will be the central angle. All of these terminologies may be getting overwhelming but just take a breath, and look at the figure illustrated below, this will clear all the doubts and concepts about arcs. Now that we know what an arc is we can move down to calculating the arc length. There is a simple relation the related the arc length, radiu...
