Let X and Y are two sets. A relation f from X to Y is said to be a function if for every x ∈ X there is a unique element y ∈ Y, such that (x, y) ∈ X
Shares and mutual funds-Share is the smallest unit of the capital of a company. In other words, A unit of ownership, that represents an equal proportion of a company’s capital is called as shares.
The consumer price index measures the amount of money which consumers of a particular class have to pay to get a basket of goods & services at a particular point of time in comparison to what they paid for the same in the base period.
Integration is the reverse process of differentiation. It is also called anti-differentiation.
Chinese remainder theorem- Once a Chinese riddle asks the following question- Is there a positive integer x such that when x is divided by 3 it yields a remainder 2, when x is divided by 5 it yields a remainder 4, and when x is divided by 7 it yields a remainder 6?
An annuity is a sequence of equal payment or a sequence of regular payment at regular intervals or in other words.
We can lent or borrow money from one entity to another. The price to be paid for the use of a certain amount of money for a certain period of time is known as interest.
Taylor series method to solve the first order ordinary differential equation- The general first order differential equation
When the changes in one variable are associated or followed by change in the other, we say that there is a correlation between the two. Such data connecting two variables is called a bivariate population.
If we get a square matrix from an identity or unit matrix by using any single elementary transformation is called elementary matrix.There are two types of echelon form of a matrix.
The determinant of a matrix is a number that associated with the square matrix. This number may be positive, negative or zero.
Sample space: Set of all possible outcomes of a random experiment is known as sample space and we denote it by S, and the
Simpson’s rules are very useful in numerical integration to evaluate such integrals. Here we will understand the concept of Simpson’s rule.
Basically correlation is the measurement of the strength of a linear relationship between two variables say x and y.
The probability of an event X, such that event Y has already happened, is called conditional probability
The inverse of a matrix is the same idea. If there is a matrix A then its inverse is written as A-1.
Numerical integration is the method to calculate the approximate value of the integral by using numerical techniques.
