MEI DIFFERENTIAL EQUATIONS:REVISION DOCUMENTS

These documents aim to help the revision of the differential equations as the are taught under the OCR MEI  specification. They are under constant improvement. There are some more which they will uploaded shortly.

A. Modelling with differential equations :construction of models
B. A flowchart for solving second order homogeneous  differential equations with constant coefficients

C. The particular integral: how to find it.
D. Euler's method revision
E. Mind map for solving first order ordinary differential equations
F. Tangent fields and isoclines: what should we be aware of.
