Definition 1 A significant digit of an approximate number is any non-zero digit in its decimal representation, or any zero lying between significant digits, or used as place holder to indicate a retained place.
Numerical Analysis (3rd ed.)
The digits 1, 2, 3, 4, 5, 6, 7, 8, 9 are significant digits. For example, in the number 0. The other two 0s are significant. Two notational conventions which make clear how many digits of a given number are significant are given below. The significant figure in a number written in scientific notation M 10n consists of all the digits explicitly in M.
Significant figures are counted from left to right starting with the left most non zero digit. Example 1.
Sometimes it may be necessary to cut the numbers with large numbers of digits. This process of cutting the numbers is called rounding off numbers.
In rounding off a number after a computation, the number is chosen which has the required number of significant figures and which is closest to the number to be rounded off. Usually numbers are rounded off according to the following rule. Rounding-off rule In order to round-off a number to n significant digits drop all the digits to the right of the nth significant digit or replace them by 0s if the 0s are needed as place holders, and if this discarded digit is 1.
Less than 5, leave the remaining digits unchanged 2.
K Sankara Rao Solutions
Greater than 5, add 1 to the last retained digit 3. Exactly 5 and there are non-zero digits among those discarded, add unity to the last retained digit However, if the first discarded digit is exactly 5 and all the other discarded digits are 0s, the last retained digit is left unchanged if even and is increased by unity if odd.
In other words, if the discarded number is less than half a unit in the nth place, the nth digit is unaltered. Condition: New. First edition.
The knowledge of classical mechanics is vital for understanding advanced technologies in several areas such as automation, industrial process control, and aerospace. The basic concepts and principles of mechanics are explained in clear, simple terms and illustrated through several examples.
Keeping student accessibility in mind, the book is written in an expository manner aimed at conveying a deep and coherent understanding of the dynamics of a system of particles, kinematics of a rigid body motion, dynamics of a rigid body in space, and orbital motion. This is followed by the description of Lagrange and Hamilton methods and the special theory of relativity.
Solved examples and exercises reinforce conceptual understanding and highlight application of principles to real-world problems. Multiple-choice questions are modelled on examination pattern of various Indian universities, GATE and other competitive examinations.

Answers to Exercises. These are the errors involved in the statement of a problem.
It is denoted by Ep. Module II 25 hrs Fermat's little theorem and pseudoprimes Wilson's theorem.
By the error we mean the difference between the true value and the approximate value.
