## Area of a Circle – Proof | Geometry | Maths | Tutorial

You may not know this but there is no way of calculating the area of a circle exactly. The area of a circle is calculated by splitting the circle into many right-angle triangles and then calculating the area of these triangles. As you know triangles have straight lines and circles are curved therefore Continue reading “Area of a Circle – Proof | Geometry | Maths | Tutorial”

## How To Use Pythagoras Theorem? | Geometry | Maths | Tutorial

This theorem proves that for a right angle triangle, the area of the square on the hypothenuse (the longest side or the side opposite the right angle) is equal to the sum of the area of the squares on the sides adjacent to the right angle.

## Emma’s Dilemma – Permutations with Unique & Repeating Letters | Maths | Tutorial

In this scenario we look at two names EMMA and LUCY, we want to find out all the possible arrangements the letters of their name can be used to make this is known as permutations. We will also learn to use a formula that will help calculate how many different combinations there are without having to write them down manually this is especially useful if there are 100’s of possibilities.

Algebra is a type of mathematics which uses letters to represent possible numbers and quantities in equations. Algebra can be useful in solving real world problems as the letters can be used to represent real things. Continue reading “How To Solve a Basic Algebra Equation – Addition | Maths | Tutorial”

## Fusing Together The SUM and Index Function | Excel | Tutorial

The purpose of the index function is to help us find the position of our data in Excel so that we can retrieve it and use it for various purposes. In this example, we will be using the Index function to find the position of our monthly sales figures from table 1 so that we can summarise it into quarterly figures.
