How to Learn Matrix for JEE

by Zachary Preston on

As far as the JEE Main is concerned, Maths is an important subject. Once learned properly, students can easily score good marks in the JEE Maths exam. They should be thorough with all the formulas and theorems in Maths. Learning the formulas thoroughly will definitely help the students to save time during the exams. Maths is a subject which has a number of tricks to find the correct answer. Students should learn these tricks so that they can easily get the correct solutions. Byhearting the solutions will not work for Maths.

Let us discuss an easy and interesting topic in maths: matrix. When we arrange numbers in rows and columns, we call it a matrix. We can say that it is a rectangular array of numbers in rows and columns. Students can expect questions from matrices for any engineering entrance exam. Students are recommended to make use of each and every available resource to learn about the matrix. In this article, we will discuss matrix multiplication properties, types, addition properties, etc.

Matrix Multiplication – Properties

Following are the properties of matrix multiplication.

  • Not commutative
  • Associative
  • Distributive
  • Zero matrix multiplication
  • Multiplicative identity

Let M is a square matrix, and N be another square matrix. We can say that MN is not equal to NM. The commutative property does not satisfy here.

Matrix Addition – Properties

Following are the properties of matrix addition.

  • Commutative
  • Associative
  • Identity
  • Additive inverse

In matrix addition, the commutative property is satisfied.

Scalar Multiplication – Properties

Let M be a matrix, and N be another matrix of the same order, and p and q be two scalars, then:

  • p(M + N) = pM + pN
  • (p + q)M = pM + qM
  • p(qM) = (pqM) = q(pM)
  • (-pM) = -(pM) = p(-M)
  • tr(pM) = p tr(M), tr denotes trace of matrix.

Matrix – Types

The different types are given in the table below.

Row matrix Column matrix
Null matrix Singleton matrix
Diagonal matrix Scalar matrix
Horizontal matrix Vertical matrix
Square matrix Identity matrix
Triangular matrix Singular matrix
Non-singular matrix Symmetric matrix
Skew symmetric matrix Hermitian matrix
Skew-Hermitian matrix Idempotent matrix
Nilpotent matrix Periodic matrix
Involutary matrix Transpose matrix

Determinant

Let A be a square matrix of order two having elements a11, a12, a21, a22. To calculate the determinant, we multiply a11 and a22. Then, multiply a21 and a12. Then, find the difference (a11a22 – a21a12). Students can expect questions from determinants for the JEE Main and the JEE Advanced. The determinant is an easy topic if learned properly. Students can easily score full marks on this topic if they learn the important formulas and properties. They are recommended to practice as many previous years’ questions as possible. It will help to improve their speed.

Time management is an important factor which determines the rank of the student in any entrance exam. Solving previous year’s questions and mock tests will help students to complete the exam within the stipulated time.

The Different Types of Search Queries: How to Optimize Your Site for Them All

by Zachary Preston on

As a website owner or manager, it’s important to understand the different types of search queries that people use when they’re looking for information online. By understanding the different types of searches, you can optimize your site accordingly and make sure that you’re providing the best possible user experience.

So, what are the different types of search queries? There are four main types of search queries: navigational, informational, transactional, and commercial investigation. Let’s take a closer look at each one:

Navigational searches are used when someone is looking for a specific website or web page. For example, if someone wants to go to the Amazon home page, they would type in “amazon” into their search engine. If someone wants to find a specific article on Wikipedia, they might type in “Wikipedia article on the history of the world.”

Informational searches are used when someone is looking for information on a specific topic. For example, if someone wants to know what the capital of France is, they would type in “capital of France.” If someone wants to learn how to make a cake, they might type in “cake recipe.”

Transactional searches are used when someone is looking to complete a transaction, such as buying a product or booking a hotel room. For example, if someone wants to buy a new pair of shoes, they might type in “shoes” or “buy shoes.” If someone wants to book a hotel room for their vacation, they might type in “hotel rooms” or “book hotel room.”

Commercial investigation searches are used when someone is considering making a purchase, but they want to do more research before committing to anything. For example, if someone is looking for a new car, they might type in “Best cars for 2020” or “cars with good gas mileage.” If someone is looking for a new laptop, they might type in “laptops under $500.”

By understanding the different types of searches that people use, you can optimize your site accordingly and make sure that you’re providing the best possible user experience. So take some time to consider what type of searches your target audience is likely to use, and then make sure that your site is optimized for them.

Some tips on how to optimize your site for different types of searches:

– Use keyword research to identify the most popular search terms that people are using.

– Use these keywords throughout your website, including in the title, meta tags, and body content.

– Create separate pages or sections for each type of search query.

– Use clear and concise titles and descriptions to help people find what they’re looking for.

– Use images, videos, and other visual elements to break up text and make it more visually appealing.

– Make sure your website is mobile-friendly and easy to use on all devices.

By following these tips, you can make sure that your website is optimized for all types of search queries, providing a better user experience for your visitors.
