Using Trace (22.1875399) & Trac (21.1875399):
60 / 6 = 10
10 / 22.1875399 = 0.45070341484
0.45070341484 / 21.1875399 = 9.54929658498
Using pi (3.14159265):
60 / 3.14159265 = 19.09859319285
19.09859319285 / 2 = 9.54929659642
*The Trace & Trac result is more accurate. Even if pi
is taken to the next place value (3.141592653), the
above result using the Trace & Trac is still more
accurate--pi must be taken to 3.1415926535 to
achieve a more accurate result (the Trace & Trac
can also be extended but it is rarely done).
