13.3 classical straightedge and compass constructions
... roots of constructible elements. We shall now see that these are essentially the only operations possible. From the given length 1 it is possible to construct by these operations all the rational numbers Q. Hence we may construct all of the points (x, y) ∈ R2 whose coordinates are rational. We may c ...

... how to use a CAS in the way required in the task. Also, highlight the warning given with question e. That is, emphasise that when entering an expression such as ax, the multiplication sign should be used, i.e. a × x. The critical part of the task involves the solution of a pair of simultaneous linea ...
