In this module, get to grips with differential equations.
Solve these differential equations to see how a minus sign can change the answer
This article covers what differential equations are, and offers some insight into how to formulate one describing a real life situation.
In STEP and other advanced mathematics examinations, two main methods are used to solve first order differential equations: separation of variables and the method of integrating factors. This article reviews how the two work.
Many modelling situations force us to deal with second order differential equations. In STEP and other advanced mathematics examinations a particular set of second order differential equations arise, and this article covers how to solve them.
Here you can find several example questions from STEP past papers for you to practice your skills on.
