COSINE GRAPH MANIPULATION GCSE 9 - 1

This resource makes simple of the complicated which is the manipulation of the cosine graph for GCSE higher tier maths 9 - 1. **With more than 50, dynamic yet detailed slides **dedicated to simply clarifying the cos graph and how to use it within the exam, it serves as the perfect introductory lesson for students, as well as an in depth revision guide for students who need some more direct help in the topic. This resource also seeks to incite some interest for some keen students who may be considering A-Level mathematics. This resource includes:

• 3 BONUS STARTERS WITH INDEPTH ANSWERS
• Explaining the key feature of the cosine graph (peaks, troughs, intercepts)
• Analysing the wave cycles of the cos graph
• Understanding the x values as angles, and the y values as constants
• Understanding that functions with inputs ( cos(60) ) is equal to its constant 1/2.
• Understanding how to manipulate the cos graph for cos (x) + 2
• Using the rules of the graph to see different inputs (60 or 360) of the same function (cos) produce the same constant.
• Use of tables for the cos graph.
• Exam style practice questions
