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.
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice.
