... mostly on mathematical matters. In his letter, Euler provides a “guessed” method for computing the number of triangulations of a polygon that has n sides but does not provide a proof of his method. The method, if correct, leads to a “formula” for calculating the number of triangulations of an n-side ...

... 6. True or False: The logarithm (base 2) function lg( x ) is not one-to-one. Explain your answer. 7. True or False: Since 210 = 1024 is approximately equal to 103 = 1000, the log base 2 of 10 is approximately equal to 3 and 1/3. Explain your answer. 8. Use the fact that 27 = 128 is approximately equ ...

... Randomness needed to imitate real life is made possible through the use of “random numbers.” Random numbers are distributed uniformly and independently on the interval (0, 1). Random digits are uniformly distributed on the set f 0, 1, 2 91. Random digits can be used to form random numbers by select ...

Approximations of π
Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.Further progress was made only from the 15th century (Jamshīd al-Kāshī), and early modern mathematicians reached an accuracy of 35 digits by the 18th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the mid 20th century, approximation of π has been the task of electronic digital computers; the current record (as of May 2015) is at 13.3 trillion digits, calculated in October 2014.
