WitCH 57: Tunnel Vision

The following is just a dumb exercise, and so is probably more of a PoSWW. It seems so lemmingly stupid, however, that it comes around full cycle to be a WitCH. It is an exercise from Maths Quest Mathematical Methods 11. The exercise appears in a pre-calculus, CAS-permitted chapter, Cubic Polynomials. The suggested answers are […]

Alan Tudge, Annotated

Alan Tudge, the Federal Minister for Education and Youth is, of course, an asshole. He is a nasty, down-punching, vindictive, glass-jawed, born to rule shithead. But, is Tudge an idiot? Yesterday, Minister Tudge gave a major policy speech – Being our best: Returning Australia to the top group of education nations. The title indicates the […]

VCAA’s Draft Feedback Due TODAY

We’ve been remiss in not writing further on VCAA’s draft for the new mathematics VCE subjects. It’s just, for reasons we’ll explain briefly here and flesh out elsewhere, we’ve struggled to face up to this new nonsense. But, feedback is due TODAY (midnight? – see links below), and we really oughta say something. So, here […]

WitCH 52: Lines of Attack

Yes, we have tons of overdue homework for this blog, and we will start hacking into it. Really. But we’ll also try to keep the new posts ticking along.

WitCH 46: Paddling in the Gene Pool

The question below is from the first Methods exam (not online), held a few days ago, and which we’ll write upon more generally very soon. The question was brought to our attention by frequent commenter Red Five, and we’ve been pondering it for a couple days; we’re not sure whether it’s sufficient for a WitCH, […]

WitCH 44: Estimated Worth

This WitCH is from Cambridge’s 2020 textbook, Mathematical Methods, Unit 1 & 2. It is the closing summary of Chapter 21A, Estimating the area under a graph. (It is followed by 21B, Finding the exact area: the definite integral.) We’re somewhat reluctant about this one, since it’s not as bad as some other WitCHes. Indeed, […]
