Composition functions are used to combined the two functions by using the certain formulas. Let A, B and C be any three sets and let f : A B and g : B C be any two functions. Note that the domain of g is the co-domain of f. Define a new function (gof): A C such that (gof) (a) = g(f(a)) for all a A. Here f(a) is an element of B. therefore g(f(a)) is meaningful. The function gof is called the composition of two functions f and g.
From the definition of rational numbers, a rational number is one that can be expressed as fraction or exactly as the form m/n where m and n are integers or whole numbers and n is not zero. Basically, the categories of rational numbers are two types that is, a rational number which has a terminating decimal and other one is which has repeating decimal.
Boolean Algebra provides a basic logic for operations on binary numbers 0, 1. Since computers are based on binary system, this branch of Mathematics is found to be useful for the internal working of various computers.The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logic.
For example, consider the equation y = 4x + 3. In this equation the value of the variable y value changes according to the changes in the value of x. Therefore the variable y is said to be as dependent variable. Some of the examples that involve dependent variables are discussed in detail as below with their solutions.
Strollers and Prams are a safe way of commuting inside a closed space like a mall especially when the baby also is very small. This ways you are not laden with a lot of weight and the baby learns to sit independantly from early on. These are easily operable, and very portable.
