최신동역학 : 최신 동역학 4판 솔루션 풀이 최신동역학 : 최신 동역학 4판 솔루션 12장부터 21장까지 족보도 있구요. Solution Homework 도 포함 Problem 12.1 The value of π is 3.1415962654. . . . . If C is the circumference of a circle and r is its radius, determine the value of r/C to four significant digits. Solution: C = 2πr ⇒ r C = 1 2π = 0.159154943. To four significant digits we have r C = 0.1592 Problem 12.2 The base of natural logarithms is e = 2.718281828 . . . (a) Express e to five significant digits. (b) Determine the value of e2 to five significant digits. (c) Use the value of e you obtained in part (a) to determine the value of e2 to five significant digits. [Part (c) demonstrates the hazard of using rounded-off values in calculations.] Solution: The value of e is: e = 2.718281828 (a) To five significant figures e = 2.7183 (b) e2 to five significant figures is e2 = 7.3891 (c) Using the value from part (a) we find e2 = 7.3892 which is not correct in the fifth digit.
