Grouped Data: Easy approach 1
In statistics, data items can be considered as a group. This approach works well when the number of records is huge. It is more efficient than considering an individual item

Set Theory 1: precise easy
Set Theory is a branch of mathematical logic that deals with the study of sets, which are collections of objects. These objects can be anything: numbers, letters, or even other sets. Set theory forms the foundation of much of modern mathematics and provides a framework for discussing collections of mathematical objects. Set Theory: Set Notations…

Pie charts: easy concise Introduction 1
Pie charts are a circular graphs. A circle is divided into sections, each representing a frequency of an item in the data set. A pie chart shows the relative contribution that different categories contribute to an overall total. They are used to show percentage or proportional data. The percentage represented by each category is provided next…

Integrating trigonometric expressions 1: Concise Easy
Integrating trigonometric expressions involves solving trigonometric expressions that contain trigonometric functions. These functions are periodical.

Bar Graphs: concise Introduction1
Bar graphs consist of vertical or horizontal rectangles. These rectangles are drawn on a Cartesian plane. They represent a particular data item with its frequency. Bar charts are especially effective with numerical data. This is when the data splits nicely into different categories. You can quickly see trends within your data. They are best used to:…

Easy Integration4: partial fractions
Integrating with partial fractions involves resolving an fractional integral into simpler fractions that can be integrated separately. Partial Fractions are the fractions that are formed when one single fraction is split into two or more simpler fractions. consider the fraction: As can be seen, the complex fraction on the left hand side has been split…

Reading meter Rule with accuracy
A ruler is a tool mostly used to measure small lengths. A metre rule has a length of one metre, which is equal to one hundred centimeters. A ruler, also known as a rule, scale and sometimes a line gauge, is an instrument used to measure lengths. A user estimates a given length by reading…

Breaking integral into Reduction Formulae2
Reduction formulae is a method of integration commonly used in solving integrals that are raised to power n. It is common in trigonometric ratios that are raised to power n. Reduction formula is obtained using implicit integration. implicit integration is the use of substitution to find the integral of y with respect to x. This…

Simple understanding of Stationary Points1.
Stationary points are points on a curve where the function is neither increasing or decreasing. That is, f(x) is not changing at the stationary point. We call it stationary because when we envision an object moving along the curve f(x), the object stops there. The object will be stopping at that point. A stationary point…
