How is math useful for programming?

>> No.7043163

>>7043147
as I was failing a simple college algebra class, i asked myself that too.

>> No.7043164

Moderately. Certain parts of analysis, discrete math, and numerical analysis are good to know. Donald Knuth is the big name in that particular interdisciplinary interface. Read his textbook "Concrete Mathematics."

Programming = Math.
Computers are made of math. Since for design of layouts you see on your screen, to calculus made to process programs and make hardware work.
If you can't/don't like doing math, then don't even try programming. Unless you want to create dumb programs that even a child could make.

Not true. My uncle is a java programmer and sucks at math but still makes a decent living. His comp sci degree required calc II which he took 3 times and an intro to combinatorics which he took twice.

To write code all you need to know is... coding! Math is just a weed out in college.

>> No.7044135

You can be a complete retard in maths and still be a "good" (whatever that means) OO programmer. Such is the world of OO programming.

>> No.7044138

if you wanna do 3d shit, you'll need some decent math

although i bet a lot of programmers today just copy pastas everyone elses code

>> No.7044148

>>7044138
No you dont. Yes there is a lot of cool math going on but a programmer can be totally unaware of it.

>> No.7044154

>>7043147
Pleb tier fart apps and whatnot? It's not. That we require software engineers to get Computer Science degrees is fucking criminal; all the education you should need is 2 years of community college or a decent portfolio.

Computer Science has nothing to do with HTML and Java. It has to do with the study and manipulation of information.

>> No.7044156

helps understanding how computers manipulate binary.

>> No.7044159

>>7044125
it also weeds out people from making 6 figures by coding. the logic in coding is mathematical.

>> No.7044169

>>7044159
There is not a lot of logic in math. Its more of a memory class remembering what equations to use and how to cancel different numbers. If programming needs logic maybe they need less math and maybe some political science or law classes?? Just an idea.

>> No.7044173

>>7044169
What you're describing is not a college math class unless you're less than six weeks into your first year.

I can tell you've never done any post-high school mathematics.

>> No.7044181

Math is insanely useful for solving problems which then can be translated into code. Code itself is trivial to vomit out.

>>7043273

Algorithm analysis is trivial as fuck.

>Its more of a memory class remembering what equations to use and how to cancel different numbers.

It saddens me that people think of math like this. All you have to do is ask "why" a forumla/expression/equation came to be, take your time actually understanding it and then math is just applied logic

>>7044173
Well I cant speak beyond calculus III but this is how they were. I have never had a test that wasnt just basically looking at your formula sheet, picking the right one and knowing how to properly use your calculator.

Only a bit in calc 2 with the series crap did it stray from that but people bombed that test so bad the curve saved me. Also the last test for calc III was a bit crazy but we got to skip vector fields which I hear are bad so maybe I am not 100% right.

But still that is all of calc I and most of calcII and III. Its all about memorizing the right tricks, lots of practice and knowing how to get data out of word problems.

math + code --> x > $100k

It probably depends on the uni and teacher, but calc as it is taught in some universities isn't even math, rather "List of calculation results that science-related people might find useful". In a decent system this should start in sophomore/junior highschool and end before freshman college. You need the proficiency with formal expressions to go further, but you also need to understand where they come from.

>> No.7044219

>>7044206
It may shock the math majors but most people who take calculus cannot differentiate by hand or find an integral without a calculator, table or laptop.

Because theyre never asked to.

That's bullshit. There's no way you could get through a calc class, even in the US, without knowing AT LEAST how to differentiate simple algebraic equations.

>> No.7044259

>>7044231
I said by hand. Though I am being extreme Im sure they can apply the power rule and do basic derivatives quotient/product rule problems and even a few chain rule, anti derivatives and a few basic integrals.

But many just plug it into their calculator. In my calculus classes we were handed a sheet with all the operations needed and in class we got more questions on how to input shit into the calculator than actual class questions.

>> No.7044261

>>7044231
At my uni, we have Analytic Geometry and Calculus classes and Calculus for Engineering and Technology classes.

AG&C is what you think of as calculus. How to find limits/derivatives, techniques for integration, infinite summations, etc. CfET is more along the lines of a tutorial path. It teaches what derivatives and integrals are, and how to use them, but not how to find them. Tables, calculators, and Matlab are in constant use. The engineering path picks up vectors and differential equations much sooner than the mathematics path, and I don't think they do summations at all.

Example AG&C exam:
>Here's a bunch of difficult integrals/summations/limits/etc. Solve them.

Example CfET exam:
>Here's a couple difficult physical situations. Figure out exactly what happens.

Im in calc I now. First month is algebra/trig review, second month derivatives then two months of applications. We take our tests in a lab with computers which were allowed to use. Wolfram Alpha is encouraged and we spent two lectures on how to input. Limits are not even mentioned we briefly learn the power/product/quotient/chain rules and how to identify them then on to solving word problems and real life "industry" examples.

"Technology school" is not engineering.
