Using function machines to solve equations Function machines can be used to solve equations by reversing, or finding the inverse of the steps.

Revise how to identify the y-intercept, turning point and axis of symmetry of a quadratic function. BBC Bitesize Scotland revision for SQA National 5 Maths.

We suggest reducing the design matrix to row echelon form as a means of finding the structure of all estimable functions. We illustrate the procedure with two examples.

A method is given for estimating the coefficients of a single equation in a complete system of linear stochastic equations (see expression (2.1)), provided that a number of the coefficients of the ...
