Ordinary Differential Equation or ODE
What is an Ordinary Differential Equation (ODE)?
Expert
It is an equation that involves an unknown function and its derivatives.
e.g.:
You should have learned how to classify ODEs by their order, degree, linearity, homogeneity, etc. (students are strongly advised to review their ?rst and 2nd year ODE courses).

Factorisation by Fermat's method: This method, dating from 1643, depends on a simple and standard algebraic identity. Fermat's observation is that if we wish to nd two factors of n, it is enough if we can express n as the difference of two squares.
(a) Solve the following by: (i) First reducing the system of first order differentiat equations to a second order differential equation. (ii) Decoupling the following linear system of equa

Factorisation by trial division: The essential idea of factorisation by trial division is straightforward. Let n be a positive integer. We know that n is either prime or has a prime divisor less than or equal to √n. Therefore, if we divide n in

Group: Let G be a set. When we say that o is a binary operation on G, we mean that o is a function from GxG into G. Informally, o takes pairs of elements of G as input and produces single elements of G as output. Examples are the operations + and x of
