Explanation of Pi (22 7 )as an Approximation of Pi
Why 22/7 is a Good Approximation
The fraction 22/7 approximates Pi closely, yielding a value of approximately 3.142857. This is quite near to Pi’s actual value of about 3.14159, with a relative error of just 0.04%. This makes Pi (22 7) a handy and straightforward approximation for many practical mathematical calculations.
Comparison with Other Approximations
Although Pi (22 7) is a popular approximation, other fractions offer even closer estimates. For instance, the fraction 355/113, used by Chinese mathematician Zu Chongzhi (429-500 AD), gives a value of about 3.1415929, which is incredibly close to Pi. Despite this, 22/7 remains favored for its simplicity and ease of use.
Mathematical Properties and Significance
Pi (22 7) is an irrational number, which means it cannot be represented as a simple fraction or ratio of two whole numbers. It is also a transcendental number, indicating that it is not a root of any non-zero polynomial equation with rational coefficients. These properties make Pi a captivating and complex constant that continues to fascinate mathematicians and scientists.
