Introduction
Complex numbers are a new addition to the 2019 STEP specification for papers 2. This module introduces you to the complex number topics included in the STEP 2 specification. This STEP 2 module consists of 4 STEP questions, some topic notes and useful formulae, a "hints" sheet and a "solutions" booklet.
STEP questions are challenging, so don't worry if you get stuck. These STEP 2 modules assume that you have already begun to develop your problem-solving skills and approach to STEP questions by working on the Foundation modules.
About this assignment
Complex numbers have been on the STEP specifications since 1987, but in recent years were only on STEP III. For 2019 onwards some of the complex number work might be tested on STEP 2.
If you are using the STEP database to find other complex number questions just be aware that many of these use de Moivre's theorem, which is not on the 2019 STEP 2 specification (it is on the STEP 3 specification).
Hints, support and self evaluation
The “Hints" file gives suggestions and some starting points on how you can tackle the questions. The "Solutions" file leads you through one possible solution, but some steps will be missing and you will still need to work through the question yourself.
