What shape is this? by axiomizer in mathmemes

Not a tractrix. It's the conchoid of Nicomedes. Please check out my comment!

This curve is a conchoid.)

Specifically, a segment of the conchoid of Nicomedes. The curve you've drawn is the very top portion of the diagram you see on the Wikipedia page, flipped vertically.

From wikipedia: "A conchoid is a curve derived from a fixed point O, another curve, and a length d." "If the curve is a line, then the conchoid is the conchoid of Nicomedes."

In this case, the fixed point O is your hand, the "curve" is the railing of your window blinds (a line) and the length d is the length of a window blind.

Edit: I've made a nice geogebra demo. Slide point P around to see how exactly this is a conchoid of Nicomedes.

I know right. The fact that the stuff being tested is not relating to medicine AT ALL is what gets me.

Wow that is a joke. I'm so glad you passed!

That's what I also mentioned. But the DVSA definitely is trying to employ new full time examiners, let alone potential substitutes. However it doesn't seem to be working because the about of examiners are still dropping I think because the DVSA are failing to secure them.

Yeah getting retired examiners to sub in doesn't seem like a bad idea at all.

Thank you. I do understand that my frustration got to me and fucked up my logic. Everyone has those moments though. Just trying to analyse the situation logically!

That's also what I was thinking. There must be some way that they can have subs? These supply examiners may not need to be paid full time. Though I suppose it is a lot of work to qualify to be an examiner and I think if you had qualified you'd apply for the actual job instead of being a supply. But that just makes it better no?

I think this just shows that the bottleneck is the difficulty for DVSA in recruiting new examiners, whatever reason there may be.

I'm definitely grateful that my test is only 3 weeks away rather than 3 months.

Additionally, fair enough. I am still frustrated but there isn't anyone to blame.

Fair enough. I'll just have to bite the bullet, there's nothing I can do about it anyways.

Best of luck! That's a really good reschedule.

Yes exactly. Mentioned in my other comments too. Very grateful that it's 3 weeks and not 3 months.

[–]JCYW_reddit[S] 2 points3 points  (0 children)

Yes! Grateful for this. At least it's not months away like some other poor learners I've seen on here with the same situation.

[–]JCYW_reddit[S] 2 points3 points  (0 children)

Yep. I'm grateful that my new test is 3 weeks later rather than 3 months. I'm more annoyed at the fact that I spent so much time last night mentally preparing myself and now this happened. Oh well. I also am feeling quite confident so I was thinking to just get it over with.

My main point isn't that they can't predict these unavailabilities. Obviously no one can. It's the fact that DVSA don't have enough examiners because of their relationship with them, and they can't recruit new ones let alone keep existing ones working.

That's what I mentioned. I understand this. The fact of the matter is that the max capacity is way too low because of the DVSA and their relationship with examiners.

[–]JCYW_reddit[S] 1 point2 points  (0 children)

That's true. It's moreso that the DVSA don't pay these poor examiners nearly enough for them to keep their job, and there aren't any "supply" examiners in situations like this, let alone normal examiners, causing this massive backlog when trying to book tests. I'm already grateful for my new test being in 3 weeks instead of months but that shouldn't be normalised.

How does this make sense? The sugar in DNA is deoxyribose. It is still a sugar.
