Trigonometry – CAST Rule


Course Intro

This course takes you through the types of Trigonometry questions you can expect to face in your final exam, specifically in relation to using the CAST Rule without a calculator.

Your teacher-in-your-pocket will walk you through each key concept that you need to know, and then she will take you through example questions one by one. All questions are taken from old exam papers and they represent a specific type of question that you will face in your final exam. You will be shown exactly how to approach the different question types and you will be given all the key points that you need to remember when faced with that particular question type.

You will be given the full set of Concept Notes, the Questions that your teacher walks you through and the corresponding Memo.

We cover the South African National Curriculum and use example questions from past IEB papers – so whether you are at a GED or IEB school, this course will make it possible for you to reach your full potential!

This course can also be purchased alongside all of the Trigonometry courses in the Trigonometry Package.

So every time you buy a course from Cerebral, YOU are making the world a better place.
