If you are into research in engineering and science, you might find it useful.

A lot Nigerians only care about making money hence they might feel that this is useless, forgetting that the technology they use daily are based on things like this equation.

GanagiBitrus:
What you are referring to is not a Quadratic Curve.

In statistics, if you plot the scores gotten by 100 students against the frequency, you will get a curved chart, but that's not a Quadratic Curve.


Such curves depicting rising & falling trends are not Quadratic Curves.

Only very few people have actually used or applied Quadratic Curves in real life.
Which is an indication that several aspects of our educational curriculum are irrelevant in real life.

I’ll agree with you on the curriculum point. However, I may not have used quadratic curves directly in real life, the basic knowledge is still helpful for understanding statistics. Without these fundamentals, many people may struggle with graphs and interpretation.

Common graph. See as people dey speak English.

It's useless lol. Even dy/dx is never applicable in any situation

This is a LIE!

Medicine is exclusive. They have cadavers to have frontline experience. Even at that, ALL Nigerian graduates are illiterates to the front line techs supporting the industry. They will always have to readjust at some point when they get there.

Now compare it with computer, mechanical, , electrical or chemical. Those guys are just solving calculations and doing practicals with outdated principles and equipments, which they only do once a while and not even majors.

You know why those Philippine and Indian tech schools are always ahead, it because they follow current industry practice. Their graduates are already intuned or have a BASIC idea of the frontline operations and tools.

They don’t teach them engineering law.

The only thing you people know about medicine is Cadavers which is only use for just 18 mths of the whole 6yrs for just Anatomy class which is just one of 16 subjects viz Human Anatomy ,Human physiology,Human biochemistry,Histo-Pathology,Chemical Pathology,Haematology,paediatrics,Obstretrics and gyneacology,Internal Medicine,Surgery,forensic Medicine,Family practice and Community Medicine.

Back to the Curve,that curve can be found in any science related course.You will encounter it in human physiology when you talk of nerve conduction action potentials more like chemical concentrations in and out of nerve cells against the nerve voltage....In epidemiology,a branch of communuty medicine we talk about epi curve to intrapolate and extrapolate the spread of disease.Each group of disease tend to have different epidemiological curve.

In a nutshell,Medicine practical is beyond the use of cadaver.Also,mathematics is virtually used in all fields,except if you dont do research at all.In research,you will used statistics which is a branch of mathematics.

Just because we use finished products, we no longer appreciate the roots.
Most of the technologies we use today have their roots in these Mathematical concepts.
The artificial intelligence many people now use for has its foundation in training a model to learn and the principle is based on linear equation Y = mX + C , quadratic equation (logistics regression) and calculus for back propagation and gradient descent. The basics of generative AI such as chat GPT is Attention Mechanism which is all about vector algebra.
Please o allow your wards to learn those mathematics concept with passion who knows, they may discover new things

Most Nigerian students dont carry out their project,dissertation and thesis themselves.How will you be a graduate and you conduct an accademic reseach successfully to qualify you for that degree without using charts and curves especially in science related field.For example,for us in medicine,you cant predict the gross possible outcome of a disease without using logistic regression as a researcher.

If you've ever traded crypto or forex, then you have used this kind of chart. Oil prices rise, oil prices fall. Dollar rise, dollar fall. It's all about this chart, incase you don't know.

See many people study maths but don't really understand the concept. That's why many of them come out to embarrass themselves that maths is useless in today's world. I usually laugh at them

Yes. I use this every month.
To track expenses and income

Quadratic equation curve

I thought it's by factorisation, completing the square and formula. I guess I forgot you can also used a graph sheet to solve it.

I don't believe you. There are much simpler arithmetics for that.

Maths sweet, leave am.

You don't need to believe me sir.
It's what a already know.
And cannot be taken from me.
Maths is my best subject.

Yes! Everyday unknowingly. Like, when action bitter sachets was 150, I used to take 8 at a time. It became 2h I reduced to 4. Now 3h, I take zero or share 1. When you plot the graph it will appear like that

When az was 1h my guy can smoke 8
Now loud is 1k u no fit buy pass 1 or 2

Trend analysis is a very important tool in troubleshooting and any form of investigation. it helps to determine when something suddenly goes out of proportion.

Eriokanmi:

Have you ever heard about Machine learning, Deep Learning and Agentic AI, what about Linear regression? Una dey cap nonsense sometimes sha. People are using this knowledge to cash out in Technology, u dey waste all your resourceful time on nairaland, only to be blaming the Government.
Here are very real situations where it’s essential:
Physics: velocity is � of position with respect to time
Economics: marginal cost and marginal revenue use derivatives
Engineering: optimizing systems, signal processing, control systems
Machine Learning & Data Science: training models relies heavily on derivatives (gradient descent)
Biology: modeling population growth and spread of diseases
So it’s not “never applicable”—it’s actually everywhere once you start modeling change.

This Thread is for Folks that don't know that
Speed=Distance over Time.... Mathematics is Practical...even when betting on sportybet,.Maths is involved!!!

No b me sha na my mumu guy

Of course. Sometimes you put your records on a chart form so you see a trend, Excel does the job pretty well. It helps to capture a trend so you know where exactly you are having issues and what to improve.

Arostar2023:
This one small na... you should be talking about Laplace transform and co . The truth is that most people in Nigerian universities and most other higher institutions doing 2-5 years programs, have no business been there. An 8 months diploma/certificate or trade program would have suffice for their needs.

Omoh, Laplace transform!
I nearly craze.
I don't even know what concern computer engineering with it.
All thanks to God.

Many times, I come to the conclusion that all the years we spent in school were to ensure that we didn’t reproduce like rabbits. It’s why illiterates use the act as a sport and countries with high literacy birth less.

Never. Simple arithmetics have been more useful. The thing these days is a distant memory which should be overwritten with a skill.

Everything you learn in school is not meant for real life application. They are meant to test & expand your brain capacity and reasoning.

When the brain is well tested, it becomes easier to apply it to solving complex tasks in real life.

Unfortunately, most jobs in Nigeria don't really require tasking the brain. We leave almost everything to God.

If you try to 'push' yourself in a workplace, your colleagues may even call you oversabi. The brain then start to die slowly and thats why we rarely innovate or invent in Nigeria.

Definitely, simply put, all AIs use this to determine the best answers to users

Yes.
Power sector, it's use in many areas like frequency and load analysis also in renewable energy

It helps you shape ur imagination on how to solve the problems balablu created😂😂😂😂😂😂

BOOKWORMLUX:
You can't teach the illiterate to think in the way school shaped you too
I bet you'll regret it if you ever choose to carry an illiterate along
School changed something about the way you think and your perception of life

In as much as school can help a lot when it comes to reshaping someone's thoughts process......it isn't a guarantee....many graduates today are a good as illiterate(if not worse) in this country when it comes to how someone thinks.....that been said, any illiterate that has passion for whatsoever he is willing to be taught will most likely achieve similar results or even much more compared to someone who was well educated in that field.

You must be trading these then


Any classes?

This is crypto based but most of us don't realize... Yes I did well in this.

How

I use the binomial curve more often in understanding process distribution in our system.

Eriokanmi:
Yes, you really know me well as my neighbour, growing up

No vex my guy!
