•Here is @sahar78 posting in steem alliance to give a guidance to users about the cents and the most important things about cents.
What is cent?
•Cent is a standard and logarithmic unit you can say that is used to check or used to measure the intervals between music.Twelve- tone equal disposition divides the octave into 12 semitones of 100 cents each. generally, cents are used to express small intervals, or to compare the sizes of similar intervals in different tuning systems, and in fact the interval of one cent is too small to be perceived between consecutive notes.
How you can use the cents for different calculations and for checking the different intervals?
•A cent is a unit of measure for the rate between two frequentness. An inversely tempered semitone( the interval between two conterminous piano keys) spans 100 cents by description. An octave — two notes that have a frequence rate of 21 — spans twelve semitones and thus 1200 cents.
•Since a frequence raised by one cent is simply multiplied by this constant cent value, and 1200 cents doubles a frequence, the rate of frequentness one cent piecemeal is precisely equal to 21⁄1200 = 1200 √ 2, the 1200th root of 2, which is roughly1.0005777895.
•The number of cents measuring the interval from a to b may be calculated by the following formula( analogous to the description of a rattle)
•If one knows the frequentness a and b of two notes.
displaystyle n = 1200 cdot log,{ 2} left({ frac{ b}{ a}} right)}
•Again another case is this that if one knows a note a and the number n of cents in the interval from a to b, also b may be calculated by
displaystyle b = a times 2{ frac{ n}{ 1200}}}
•If you people talk about the US then penny and cent are the same things there. A cent is1/100 of a bone,in other words, there are 100 cents in a bone numerous other currencies have a cent as well, including the European Union, Estonia, and Hong Kong, representing1/100 of the introductory unit of plutocrat.
Why is 1 cent called a penny?
The word" penny" came from the British denotation of the same name. And since British pennies were extensively circulated throughout the American colonies( and were still considered legal tender) during the nation's foremost times, the British term stuck to our own bobby coin of analogous face value.
Thank you all ❤️
