Open interval  If a and b are two real numbers such that a < b, then the set of all real numbers x satisfying a  x  b is called an open interval  and is  denoted by (a, b) or ]a, b[ .   Thus,  (a,b) = (x: x ∈ R, a < x < b).

Ordered pairs                An ordered pairs consists of two objects or elements in a given fixed order.  For example, if A and B are any two sets, then by an ordered pair of elements we mean a pair (a, b) in that order, where a ∈ A, b ∈…

Difference of sets Let A and B be two sets. The difference of A and B written as A – B, is the set of all those elements of A which do not belong to set B Thus A – B={ x : x ∈ A and x  ∉ B} or  A – B={ x…

Function as a machine A function can also be regarded as a machine that gives unique output in set B corresponding to each input from the set A just as the function ‘machine’ shown in Fig. 2(b). Which generate an output  y = 2×3 + 5 for each input x. Fig. 2(b)          Usually real…

First Law for a Closed System Undergoing a Quasi-static process In many occasions it is necessary to consider a system undergoing a process rather than a cycle. The equation, ∮ dQ − ∮ dW = 0 is applicable during the system undergoing a cycle, and algebraic sum of all energies transfer across the system boundary…
