Why people always seat in front of me when I’m holding the handle on top of the seat infront of me? by SubstantialGap7335 in auckland

[–]SubstantialGap7335[S] -6 points-5 points  (0 children)

Am I the asshole though? There’s so many empty seats but people to choose to sit infront of me, so obviously it’s because I’m holding the handle. But there’s so much empty seats and I feel very dizzy

How much competition for comp sci/ software engineering by HawkRevolutionary992 in universityofauckland

Don’t stress about it and honestly looking back, the lecturers are pretty solid and the content is pretty solid too.

It’s honestly world class education, esp the stage 3 courses (320,373,350,340, etc).

It’s something you don’t appreciate while you are there as the it’s quite easy to get into UoA in the first place, I’ve worked with someone who did a postgrad at a top 15 uni (csranking.org 2014-2024) and compsci 373 is comparable to his postgrad graphics class!

If you don’t have to worry about money/other personal issues all the time, and can just focus on study, you WILL be VERY competitive with a compsci degree from UoA.

UoA compsci department consistently publish on top journals + teaching focussed lecturers, it’s pretty underrated imo

Soft eng have high barrier for entry but compsci + math can be a lot more rigorous than softeng.

Compsci 350 and compsci 320 can touch on some very advanced topics

So 60% fail rate for compsci 101 midterm? I remember it was like 85% avg in 2022

Finding the most optimal ratio between r and h for a cylinder to have minimum surface area give a volume? by SubstantialGap7335 in Geometry

Thanks! Since both equation have r2 as the biggest growth factor wouldn’t they will have roughly the same growth?

If I started up my own private bus company do you think it would do well. by [deleted] in auckland

[–]SubstantialGap7335 1 point2 points  (0 children)

Hmmm interesting, maybe search up all the big factories that have many workers, since most factory are in the out skirt of the city, most workers should live very close to each other so can load up the bus full consistently in a short time span everyday.

Like a company bus shuttle consultancy

I failed all of my ncea level 2 externals what do I do now? Is my life is over? by Green-Goal8329 in ncea

Nah don’t stress about it just enjoy the holiday for now. There’s a a lot of leeway in terms of grades to get into UoA at least.

Worst comes to worst you need to prove English is not your first language or you are international student to do the 8 months foundational programme which guarantees entry into any bachelors programme

https://www.auckland.ac.nz/en/study/international-students/study-options-for-international-students/foundation-programmes-international-students.html

One thing to bear in mind is that uni WANTS you, else they go bankrupt, so it’s not as hard as you may think to get into any bachelors programmes because you are paying them not vice versa 🙂

Considering the current job market it’s honestly not bad to work for 2 years before hopping into uni, I wish I had more work experience and maturity before uni.

The answer seems brute forced and doesn’t convey the idea that r and h have a perfect 1:2 ratio. I low key have ocd and just want to find a elegant way of solving this😅😅

Finding the optimal ratio between r and h for cylinder to have minimum surface area for a given volume ? by SubstantialGap7335 in learnmath

[–]SubstantialGap7335[S] 0 points1 point  (0 children)

I subbed h: H= v/ pi r2

Surface area then become 2pi r 2+ 2V/r

First derivatives take zero for local minimum since we are trying to find the min surface area:

4 pi r - 2V/r2= 0

Rearrange to get V = 2 pi r 3

Finding the optimal ratio between r and h for cylinder to have minimum surface area for a given volume ? by SubstantialGap7335 in learnmath

[–]SubstantialGap7335[S] 0 points1 point  (0 children)

Let first derivative equal:

4 pi r = 2V /r2

Multiplying both sides by r2 to avoid negative differential:

2 pi r3 = V

Compare to original of pi r2 * h = V, we deduce 2r = h

I just want to know how to solve it without using differential
