pleeeeeb

>>6189236
what book OP?

ciphers and cryptography seem cool

Is that Compsci?

>>6189261
Coz Its in my habit.I can self-study more than I can listen to teachers.Is this a psychological problem? I fail in exams though coz before exams I am still researching on topics on books and internet.

>>6189302
>I fail in exams though

studies even during holidays, fails on exams anyway. blames it on research.

what a retard.

>>6189261
I don't learn everything from lecture/class notes.

In fact I don't know why I even take any because I don't even look at them 99% of the time.

I usually end up teaching myself everything from the book.

>>6189309
I can't remember all the stuffs at a time.

>>6189277
Nice dubs and yeah its Compsci.

Pretty sure the action of taking notes helps you memorize them.

im doing fourier series in math, i would mention i'm also doing laplace transforms but it really isn't worth mentioning because it's piss easy. fourier isn't because i haven't invested enough time in it.
im doing statistics also, it blows huge dicks because my interest in statistics is about zero.

also motors and generators on the side, synchronous, direct current and induction motors.
some people i worked with while working with a synch motor turned a wrong dial once and the speed of the rotor tried to reach infinity. the lab engineer literally threw himself at the machine to try and fix it before it literally flew off its hinges.
it was fun

also control engineering.
work with plc and various circuits that in some way involve opamps and wheatstone bridges.

it's alright in general i guess.

this sounds like such a blog but you asked for it :)))

Retard. They're the same thing

>>6189528
u wot m8

>>6189319
It's way less productive because it takes a lot more time to learn the things you need to know.

>>6189528
yes in the sense that fourier only takes the imaginary parts of laplace

not exactly the same thing though
basically all the transforms are different, but major properties stay the same

>>6189546
>yes in the sense that fourier only takes the imaginary parts of laplace

No retard.

>>6189567

you make compelling arguments.

One day I will get accepted into university and leave my life of retail and dishwashing forever!

Oh my it has been years since the last time I touch a physical copy of any book in my courses

Cohomology of algebraic vector bundles

Almos goddid
Iss p. hard dough

>>6189519
Fourier is just as easy as Laplace, you just need to get used to it like you did with Laplace.

>>6189528
Wrong, they are completely different, Laplace uses s domain, fourier uses the i domain.

They are the same in the sense that they try to accomplish the same thing, but they are not they are completely different and produce different results.

>>6189546
Also incorrect.

Travelling salesman problem, exact solution and approximate solution. I already wrote a nice 2 loop implementation of Prim's Algorithm for minimum spanning trees.

> Linear algebra is the study of linear maps on finite-dimensional vector spaces. Eventually we will learn what all these terms mean.

>>6190504
linear algebra isn't so hard. I am legitimately retarded and am doing well in the class.

>>6190508
I'm more doing it to get introduced to formalism.
I've taken a couple engineering courses using it.
I just can't translate that first sentence yet.

>>6190508
>linear algebra isn't so hard

Not so much if you got a decent professor. This one prof just did arbitrary Gaussian eliminations for most of his lectures but his tests consisted of proofs and a hell lot of theory. The class averages were in the 60% and 50%. fucking nightmare.

What textbook are you using? and would you recommend it?

>>6189393
Judenschwein.

>>6189927
how old are you

>>6191307
21

Am I now too old to go to university?

Linear algebra, linear transformations, inner-product spaces, and it's very proof-heavy.

exam in 12 days, and I've got one hard exam before that...

>>6191357
Yep. There's an age limit for going back to school, if you apply you will be arrested.

Help me out niggers

>>6191357
Nah. There isn't an age limit.

>>6191432

the vertical bar stands for pipelining

you need to pipeline your functions in your gentoo terminal

press alt+t and pipeline, use the map function and pipeline your f's into the machine.

trust me i'm from /g/

>>6189393

>pipelining

u wot m9?

>>6191432
looks interesting

is this for the end of a real analysis course or functional?

>there are people on /sci/ who actually try to learn from inferior sources like lectures and shitty notes when they could just read the book and gain a deeper understanding.

>>6191526
>confirmed for never having a good lecturer ever
2bad4u
Good lecturers are a great resource.

>>6191534
There's no such thing as a perfect lecturer. You can understand stuff much better and much more efficiently if you have time to think about everything as it is brought up. With lectures, they just move on to the next subject and if you have something that you're still thinking about, you get left behind. And of course if they go too slow, then you're just bored.

>>6191538
the key is to both attend lectures and try to understand the material on your own, both before and after the lecture.

>>6191548
But if I understand the material by reading it beforehand, whats the point in going to lecture?

>>6191550
>not enjoying a well-delivered lecture

Also some teachers like to include things that they see in class on tests, I do it sometimes. Freebie for those who attended.

>>6191552
No thanks I'll stay home and play video games

>>6191550
There might be some parts you overlooked or simplified. But the most important is that you then have your questions ready for the parts you didn't understand.

End of real analysis (analysis III for me) I got metric spaces and differentiation next term and both of them lead to functional analysis next year so I'm not there yet.

>>6189236

Math grad student here. Studying pseudo-differential operators.

>>6189319

Yeah I never read my notes. I prefer reading a good text. But I think taking notes helps you remember the stuff.

>>6189528

So the Laplace transform maps Schwartz space into itself?

I didn't fucking think so.

dentistry

but actually would like to study math and economics aswell

Have a semester-long lab report due on my independent research, three mini-lab reports due for the bioinformatics portion of my genetic engineering class, and an essay-paper for my proofs class, pic related (I've already figured it out). The essay is actually fun, primarily because I figured it out quickly, so obviously I'm doing that first because I'm a procrastinator.

Statistics 1 (International) (Cambridge International Examinations)

They only got bad quality photos online.

>>6192786

Hmm and would I recommend it? Hmm, well are you doing CIE A Levels, then yes it would most likely be the best fit. Got some good questions in there, explaining could be a little better, but if you get stuck just use Google to check your answer.
There seem to be a lot of people posting questions from this book on Yahoo answers, mostly the probability chapters.

Regional geography. I hate Thailand/Philippines/Moluccas with a burning passion now.

>I enjoy it but can't take course on it because I sucked in high school (particularly at maths).

I'm restricted to wiki, sixty symbols and google.

Anything else you guys can suggest?

>>6192817
Did not mean to kill thread...

>>6192817
Can't you go to night school and redo maths?

>>6192817

Take online courses?
What >>6192854 said also seems like a good idea. If you have those kind of schools in your area.r

>>6192817
Try Saylor.org and ALISON institute.

>tfw I don't know anything about biology/chemistry past high school.

Its embarrassing

You seriously need to grow the fuck up. For some people, it helps to write out each step, no matter how trivial it may seem. I know that I often make sign errors and the like when I don't.
