Transcriber's Note: The Greek alphabets are represented within square brackets. For example, [alpha] stands for first Greek alphabet alpha. Square root of a number is represented using the symbol (sqrt). That is to say, sqrt(25) stands for square root of 25. The superscript is shown with carat (^) symbol, example, 10^{5} stands for 5th power of 10. Similarly, subscript is represented by underscore (_) symbol. For instance, n_{3} stands for letter n with subscript 3.
