Introduction 

We know how to solve linear equations and quadratic equations, either by factorising, by formula or by completing the square. In some instances, it may be almost impossible to use an exact method to solve an equation for example, 0 sin1 = −− θθ precisely. In such cases, we may be able to use other techniques which give good approximations to the solution. In this unit, we reconsider such approximations in a more formal way.
