Year 13/A2 Pure Chapter 3.6 (Sequences and Series)

How do we deal with - or even interpret - series questions involving the sigma (Σ) symbol? All is explained in this video, again through the medium of several worked examples. I also show you how these questions can be done and checked using the Casio Classwiz calculator, which will be very useful for your exams.

This lesson is meant as preparation for Exercise 3F, page 77 of the Pearson Edexcel Pure Mathematics Year 2/A2 Textbook.
