The various terms related to statistics are discussed using examples. Data: The collection of information in the form of numerical figures, regarding different aspects of life is called data. The data can be about population, birth, death, temperature of place during a week, marks scored in the class, runs scored in different matches, etc. We […]
Real Life Statistics
In real life statistics, we come across numerical data in the newspapers, magazines and television regarding different aspects like increase or decrease in population, profit made by a company in different years, weather report, etc. These numerical facts are also represented by graphs which are easy to understand. Definition of statistics: The term statistics is derived […]
Antilogarithm
If log M = x, then M is called the antilogarithm of x and is written as M = antilog x. For example, if log 39.2 = 1.5933, then antilog 1.5933 = 39.2. If the logarithmic value of a number be given then the number can be determined from the antilog-table. Antilog-table is similar to […]
Common Logarithm and Natural Logarithm
Here we will discuss about the common logarithm and natural logarithm. In Logarithm we have already seen and discussed that the logarithmic value of a positive number depends not only on the number but also on the base; a given positive number will have different logarithmic values for different bases. In practice, however, following two […]
Logarithm
In logarithm we will practice different types of questions on how to solve logarithmic functions on log. Solved examples on logarithm will help us to understand each and every log rules and their applications. Solving logarithmic equation are explained here in details so that student can understand where it is necessary to use logarithm properties […]
Logarithm Rules or Log Rules
In mathematics logarithm rules or log rules we have discussed mainly on logarithm laws along with their proof. If students understand the basic proof on general laws of logarithm then it will be easier to solve any types of questions on logarithm like ……… How to solve logarithm equations? There are four following math logarithm […]
Convert Exponentials and Logarithms
In convert Exponentials and Logarithms we will mainly discuss how to change the logarithm expression to Exponential expression and conversely from Exponential expression to logarithm expression. To discus about convert Exponentials and Logarithms we need to first recall about logarithm and exponents. The logarithm of any number to a given base is the index of […]
Mathematics Logarithms
In mathematics logarithms were developed for making complicated calculations simple. For example, if a right circular cylinder has radius r = 0.375 meters and height h = 0.2321 meters, then its volume is given by: V = A = πr2h = 3.146 × (0.375)2 × 0.2321. Use for logarithm tables makes such calculations quite easy. […]
Equivalence Relation on Set
Equivalence relation on set is a relation which is reflexive, symmetric and transitive. A relation R, defined in a set A, is said to be an equivalence relation if and only if (i) R is reflexive, that is, aRa for all a ∈ A. (ii) R is symmetric, that is, aRb ⇒ bRa for all […]
Transitive Relation on Set
What is transitive relation on set? Let A be a set in which the relation R defined. R is said to be transitive, if (a, b) ∈ R and (b, a) ∈ R ⇒ (a, c) ∈ R, That is aRb and bRc ⇒ aRc where a, b, c ∈ A. The relation is said […]
