This is a ready to teach lesson on how to implement the Simplex Algorithm and why it works, referring back to graphical and algebraic approaches. It is unclear to many students why the Simplex Algorithm works, what theta values are and why you need to look for the most negative value in the last row. The primary objective of this lesson is to thoroughly explain all of this. First, a simple problem is solved using normal linear programming, then this problem is solved using using the Simplex Algorithm, relating this back to what each and every step represents, both graphically and algebraically. The lesson is 35 PPT slides long, with tableaux for the students to work through at the same time. The lesson is provided in PPT, Notebook and PDF format. I will soon be uploading the next lesson for Simplex Algorithm so watch this space.

This is a PowerPoint presentation which uses animation, simple layouts, graphics and diagrams to clearly explain all topics required for a full understanding of Decision Maths Year 1, The simplex algorithm. This is completely in-line with the Edexcel A-level Further Maths specification. teachingisgood is happy to declare that this presentation also includes loads of practice questions, which build up a key understanding and build exam skills, as well as exam-style questions which push problem solving skills with questions aimed at the highest achieving students. This presentation is part of a series of presentations for A-level Further Maths, some of which also include interactive quizzes, videos and fun ways to test students and develop knowledge. The topics covered in this presentation is as follows. Formulating linear programming problems The simplex method Problems requiring integer solutions Two-stage simplex method The big-M method

PowerPoint to teach A Level Further Maths Decision/Discrete Maths Option: Two-Stage Simplex Algorithm (artificial variables). Primarily written for Edexcel but suitable for OCR specifications. Complete, step-by-step approach with worked examples of A Level standard. Format is such that students can also use as revision at their own pace and includes a handy flowchart for revision. The full set of 16 PowerPoints in this series cover the whole of the Edexcel D1 course: Algorithms Bin-Packing Algorithm Critical Path Analysis (GANTT) Dijjkstra’s Shortest Path Algorithm Floyd’s shortest distance algorithm Graphs & Networks Kruskal’s Minimum Spanning Tree Linear Programming Planarity Algorithm Prim’s Minimum Spanning Tree Route Inspection Algorithm Simplex Algorithm 1 - Edexcel tableau Simplex Algorithm 2 (artificial variables) - Edexcel tableau Simplex Algorithm 3 (Big M method) - Edexcel tableau Sorting Algorithm: Quick-sort, Bubble-sort (& Shuttle-sort for OCR) Travelling Salesperson Problem, including Nearest Neighbour Algorithm (+ tour improvement algorithm for OCR) Updated 2022

These two PowerPoint presentations fully explain the ideas behind the Two-Stage Simplex and the Big-M Algorithms. They both provide clear, animated, step-by-step examples explaining how to apply the algorithms. [ I have also separately uploaded a free preview so that you can see the style of the presentation. ] Slack, surplus and artificial variables are explained, as is the creation of the additional objective function (i.e. A = “The total of the artificial variables”), and the modification of the original objective function when using the Big-M method. The slides can be used as the basis for teaching the topic to an A-Level mathematics class, and they also clear enough to be used as a revision/self-study aid. For example, "triggers " are used to show how values within a tableau are calculated using row operations on the previous tableau. Extensive use has been made of PowerPoint’s animation features such as “appear”, “fade” etc… I hope this resource will be useful within your teaching, and I would happy to receive any feedback that you might have. Regards and best wishes Gerard

This A-Level Decision Maths Simplex Algorithm worksheet leads to mastery and develops deep order thinking into the hows and whys of Simplex. Featuring both closed and open questionning, the worksheet explores the ‘behind the scenes’. Students are expected to consider the alogorithmic steps, graphical representations, integer/non-integer solutions, forming questions from the answer, optimisation, constraints, variation of questionning, the use of ICT and has recommended extensions provided. Answers are provided on the second page but some are suggestions as there are open-ended questions. The format is in the Edexcel style.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It has numerous applications in physics, engineering, and technology, making it an important subject for students to understand. In this article, we’ll provide a comprehensive overview of trigonometry and explain some simple examples that demonstrate its key concepts. What is Trigonometry? Trigonometry is the study of triangles and their properties. It deals with the relationships between the angles and sides of triangles and how they can be used to solve problems in real-world scenarios. The subject is divided into several branches, including plane trigonometry, spherical trigonometry, and analytic trigonometry. Key Concepts in Trigonometry There are several key concepts in trigonometry that are essential for understanding the subject. Some of the most important concepts include: Triangles: A triangle is a two-dimensional shape that is formed by three points. Triangles are the basis for all trigonometry, as the relationships between their sides and angles are what the subject is all about. Angles: An angle is a measure of the amount of rotation between two lines or rays. In trigonometry, angles are used to define the relationships between the sides of triangles. Sides: The sides of a triangle are the lines that connect the vertices. The relationships between the sides and angles of a triangle are the key to understanding trigonometry. Trigonometric Functions: Trigonometric functions are mathematical functions that describe the relationships between the sides and angles of triangles. The most common trigonometric functions include sine, cosine, and tangent. Simple Examples of Trigonometry Trigonometry can seem like a complex subject, but it’s actually quite simple once you understand the key concepts. Here are a few examples that demonstrate how trigonometry can be used to solve real-world problems: Example 1: Finding the Height of a Building Suppose you’re standing on the ground and you want to find the height of a tall building. You can use trigonometry to solve this problem. To do this, you’ll need to take a measurement of the angle between the ground and the top of the building, as well as the distance between you and the building. Using the sine function, you can calculate the height of the building by dividing the measurement of the angle by the distance. The formula for this calculation is: height = distance * sin(angle) Example 2: Finding the Distance Between Two Points Trigonometry can also be used to find the distance between two points. For example, suppose you want to find the distance between two points on a map. To do this, you’ll need to know the coordinates of both points and the angle between them. Using the cosine function, you can calculate the distance between two points by using the following formula: distance = square root of (x2 - x1)^2 + (y2 - y1)^2

Simplex Algorithm topics covers; Identify when the simplex algorithm should be applied (ie for situations that have three or more basic variables) Introduce and use slack variables to convert inequalities into equalities (only less than or equal to inequalities will be used during assessment) Use the simplex algorithm to maximise an objective function subject to linear constraints Use the simplex algorithm to minimise an objective function P by maximising the objective function Q = –P understand and use the stopping condition for the simplex algorithm (ie the objective row being non-negative) Find the optimal value of the objective function from a simplex tableau Identify any basic or slack variables that have zero values Find the values of any basic or slack variables that have non-zero values Interpret a Simplex tableau at any stage of the algorithm. Convert higher order games to linear programming problems and solve using the Simplex algorithm These PowerPoints form full lessons of work that together cover the full A level Further Maths course for the AQA exam board.
