Pie Charts An important part of decision making is having a clear understanding of the information used to base decisions from. Charts can be valuable when a need to represent numerical data would benefit communicating information visually. Some of the most important aspects of a good chart are to select the right type of chart (or graph) that can best characterize the data‚ also‚ to keep the design simple in order for an audience to easily understand the information. One of the most popular types

π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle’s circumference to its diameter in the Euclidean plane; this is the same value as the ratio of a circle’s area to the square of its radius. It is approximately equal to 3.14159265 in the usual decimal notation. Many formulae from mathematics‚ science‚ and engineering involve π‚ which makes it one of the most important mathematical constants. π is an irrational number‚ which means that its value cannot be

inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents a different interatomic spacing in the graphite lattice structure. As we increase the voltage of the potential difference in intervals of .5kV from 2.5kV to 4.5kV‚ the diameter of the interference pattern will decrease

The termites’ reaction to pheromones in different colors of ballpoint pen ink. Abstract: We conducted the experiment with termites in order to determine how they react to pheromones present in different colors of ballpoint pen ink. The experiment consisted of two parts: in first part we used a ballpoint pen with blue ink‚ in second – a ballpoint pen with red ink. The reaction of termites was measured by their performance in 1 minute. Every termite in experimental group went through 3 tries in each
