How do you calculate a geometric sequence? The formula for the nth term of a geometric sequence is a_n = a_1 * r^(n-1), where a_1 is the first term of the . 1.Let z 1 z 2 ::: z n be points in the complex plane and. Techniques to express \in terms of zonly" is likely also to be done in week 5 in the lectures. In some questions the term harmonic appears and the connection between analytic functions and harmonic functions is likely to be covered in about week 5. Yes More Mr.Exercises involving analytic functions, harmonic func- tions ….Maths Anxiety Is Not a Thing, But Let’s Talk About It Anyway.If there is ever a time to be quietly respectful of educational authority, it is not now. (Yes, MAV, we’re talking about you, and not only you.) There is an obligation for professional organisations to encourage dissenting voices, and of course it is reprehensible for such organisations to attempt to diminish or outright censor such voices. Collegiality is valuable, and it is obviously rude, pointless and damaging to nitpick over every minor disagreement. But collegiality should be a principle, not a fetish.Īt a time when educational authorities and prominent “experts” are arrogantly and systemically screwing things up there is a professional obligation for those with a voice to use it. It is also clear, however, that many teachers and academics believe that complaining, either formally or publicly, is simply not nice, not collegial. Such fear is an argument, though not a clinching argument, for remaining silent. The VCAA has always struck us as petty and inept and devoid of empathy and plain dumb, but not vengeful. They do not trust the VCAA, for example, to not be vindictive. More than a few teachers have indicated to us that they are fearful of speaking out. If all those who were pissed off spoke up it would be pretty noisy and pretty difficult to ignore. That may well be true, though it may also be self-fulfilling prophecy. Many feel that any objection is pointless, that there is no hope that they will be listened to. Rarely are these people willing to formally or publicly express any such opinions, even if they have a natural platform for doing so. ![]() There is no shortage of people happy to acknowledge privately their frustration with or contempt for the Australian Curriculum, NAPLAN, VCE, AMSI, AAMT, MAV, teacher training, textbooks, and on and on. Which brings us to Australian mathematics education. There is so much godawful crap around and there are plenty of people who know it, but not nearly enough people willing to say it. ![]() The underlying issue, a misguided concern for collegiality, extends far beyond one stupid video. Numberphile made a bad mistake in posting that video, and they’re making a much worse mistake in not admitting it, apologising for it and taking it down. The video has been viewed over six million times, with the vast majority of viewers having absolutely no clue that they’ve been sold mathematical snake oil. Numberphile’s video is mathematical crap and it continues to do great damage. Fundamentally, the objections were to Mathologer’s engaging in strong and public criticism, to his lack of collegiality, and these objections were ridiculous. Mathologer had every right to hammer Numberphile hard. (Although, awarding Numberfile a score of -1/12 for their video is pretty funny.) But whining about Mathologer’s tone was mostly a cheap distraction from the main point. And it’s true, Mathologer’s video might have been improved without the snarky jokes from that annoying cameraman. Many others, however, while begrudgingly accepting there were issues with the Numberphile video, strongly objected to the tone of Mathologer’s critique. Many who objected to Mathologer’s video were Numberphile fans or semi-literate physicists who were incapable of contemplating the idea that Numberphile could have gotten it wrong. Mathologer’s video has been very popular (17K thumbs up), and very unpopular (1K thumbs down). As well as carefully explaining the underlying mathematical truth, Mathologer tore into Numberphile for their video. Mathologer recently posted a long video addressing the “ proof” by Numberphile of the “astounding result” that 1 2 3 … = -1/12.
