admin Previously, you learned about the concurrency mechanism in database. You know that the concurrency is maintained in a serialized manner, giving the impression that there is indeed some concurrency. The locking technique has to do a lot with this achievement of efficient access to database. What is a Lock? A lock is a variable associated … Read more
Rational functions are special functions that you cannot call polynomials, but are obtained by dividing polynomials. In other words, they are the quotients of the polynomial division. A rational function is of form where and are polynomials and . The domain of rational function can be any real numbers except those that makes . Example … Read more
In the previous article, where we introduce polynomials, a brief introduction to the roots of quadratic equations were discussed with some examples. Now you are going to learn the zeros of polynomial in more detail. The idea of zero is that to find those x values for which and it is the x-intercepts in case … Read more
You can divide a polynomial just like numbers and dividing a polynomial will give an expression as quotient and remainder. The polynomial you are going to divide must have more terms than the divisor, else the division will not be fruitful. In this article, you will learn about polynomial long division and synthetic division techniques. … Read more
Certain functions are symmetric in nature and quadratic function is one of them. If you remember from previous articles, we classified the functions as even and odd which means even functions are symmetric over y-axis and odd functions are symmetric over x-axis in a 2d coordinate plane. What is a quadratic function ? A quadratic … Read more
An object can be passed to a function just like we pass a structure to a function. we can pass the object of another class to a function of a different class. We can pass class objects as arguments and return them from a function. When we want to initialize all data members of an … Read more
The concurrency control concept comes under the Transaction in the database management system (DBMS). It is a procedure in DBMS which helps us control two simultaneous processes to execute without conflicts among every other, these conflicts occur in multi-user systems. Concurrency explains executing multiple transactions at a time. It is required to increase time efficiency. … Read more
In this article, you will learn about a special function called polynomial function. You can think of polynomials as an expression made of variables, exponents, and constants. Here the number of terms are important, hence, the name “Poly” which means “many” and “nomial” means “terms”. Standard Form The standard form of polynomial function is in … Read more
What is a file pointer? A pointer is used to handle and keep track of the files being accessed. Every file maintains two pointers called get_pointer (in input mode file) and put_pointer (in output mode file), which tells the current position where reading or writing will take place with the use of opening modes and … Read more
File streams are the libraries which are utilized in programming. These use the iostream preferred standard library because it offers cin and cout strategies which are used for analyzing from the input and writing to the output respectively. A file is a collection of associated data stored in a particular area on a disk. The … Read more
