This module introduces you to STEP 3 differential equations questions.
Each STEP 3 module consists of some 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 3 modules assume that you have already begun to develop your problem-solving skills and approach to STEP questions by working on the Foundation modules and the STEP 2 modules.
About this assignment
More complicated differential equations are included in the STEP 3 specifications, including integrating factors, second order differential equations and coupled first order simultaneous differential equations (predator-prey systems).
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.
You can read more about differential equations in this Plus Maths article.
