If the equation is ﬁrst order then the highest derivative involved is a ﬁrst derivative. If it is also a linear equation then this means that each term can involve y either as the derivative dy dx OR through a single factor of y. Any such linear ﬁrst order o.d.e. can be re-arranged to give the fol-lowing standard form: dy …

Accordingly, multistep methods may often achieve greater accuracy than one-step methods that use the same number of function evaluations, since they utilize more information about the known portion of the solution than one-step methods do.A special category of multistep methods are the linear multi-step methods, where the numerical solution to the ODE at a specific location is expressed as a linear …

A-stable numerical methods “Stiff” differential equations arise in many modelling situations’ For example time dependent partial differential equations, approximated by the Method of Lines, and problems in chemical kinetics with widely varying reaction rates. Stiff problems are characterised by the existence of rapidly decaying transients.

The order of a diﬀerential equation is the highest order derivative occurring. Equation (2.2), as (2.1), is a matrix form of a kinetic equation of a multi-step reaction. One should pay attention that a rate constant matrix always is a square matrix. A solution of (2.2) is written as CðtÞ¼exp kt C 0; where C 0 is a vector of substance initial concentrations.
