Definite Integration Involving Modulus Function There is no anti-derivative for a modulus function; however we know it’s definition Thus we can split up our integral in two parts. One part must be completely negative and the another must be completely positive. This strategy is known as splitting . To split …
In this article , some important algebra questions asked in SSC CGL previous year papers are discussed with explanations. 1. If then find (i) (ii) (iii) (iv) Sol. Given . Squaring both sides we get, . Hence (i) Now = Putting , we get = =1 …
The Greatest integer function is defined as , where denotes the greatest integer that is less than or equal to . In set notation we would write this as . It is also called the floor function and step function. Example. , and Domain and Range of …
Squaring of numbers means multiplying a number by itself. There are various formulae used in general mathematics to square numbers instantly. Let us discuss them one by one. (i) This formula is generally use to square those numbers which are near multiples of 10. For example , suppose we have …
A number is said to be divisible by another number if the remainder is zero. Divisibility rules or divisibility tests are a set of general rules that are often used to determine whether or not a number is completely divisible by another number. In this article, some divisibility tests are …
