Education

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.

Understudy loans are without a doubt an incredible monetary guide for the individuals who can’t stand to subsidize their schooling. In any case, these various advances trouble understudies with overpowering obligations before long they move on from school. Composing more than one reimbursement really take a look at consistently, in the earliest reference point of a vocation, is close to inconceivable.

For this situation most of the private advance banks are not able to give any longer understudy loans or combine them.

A few banks disposed of private credits to move into the government programs. The withdrawal of private credits for some monetary foundations implied a gigantic misfortune for business which securitizes private understudy loans.

What can Understudies and Guardians do in this Monetarily Diminished Market?

President Hedge has marked the “Proceeding with Admittance to Educational Loan Act”, which will extend qualification and the sum to be acquired from Government family Instruction understudy Loans, Administrative Understudy Loans and Parent Credits.

Consider colleges that are nearer to home, all things considered in the event that one can remain at home as opposed to a residence to save money on cost. The cash saved can be utilized for books and study material rather then food and lodging.

Despite the fact that there might be a lot of worry in the market of late. The Instruction Office says that regarding 7 million understudies will require more than \$68 billion in government advances for training this coming school year. The Instruction Office will guide government assets to state-level insurance organizations, and the assets would then be dispensed straightforwardly to universities and understudies. There will be new, higher cutoff points on sums understudies can get under government instruction advance projects. On normal these cutoff points are \$3,500 for first year, \$4,500 for sophomore year and \$5,500 every year after that. As indicated by revealed subtleties, under the new understudy loan charge, these yearly cutoff points would be expanded by \$2,000.
