Re: MATH1131 help thread

Depends on the company., I've seen a guy who is an engineer at google with no university degree.

Yes but c'mon most of us here are not engineer/programming prodigies and will most likely need to satisfy the hiring requirements of Google, and many other companies. I've heard from a person applying for a grad position, that most of the companies do indeed require a credit average. And I'd rather be safe by getting a credit average than having to settle for the small amount of companies that don't have that requirement.

Not having that credit average at a company that has it as a requirement could end up in with your resume just chucked away as they sift through the hundreds of applicants, so you don't even get an interview.

I didn't say credit average won't help you. It certainly will. But you have to find a balance between marks, real world experience and developing people skills. That's all I am saying.

I thought by you saying "depends on the company" you meant that a credit average is not usually a requirement, and that marks don't matter at all (by you bringing up an example of someone with 0 marks) - and that's what I was responding to.

I just meant some companies will make exceptions.

Re: MATH1131 help thread

there are some cute girls in comp1917


find yourself a mrs. leehuan

Lmao ok.

Why do you need someone to do it with you lol? If you're looking for fellow people doing the subject, you'll find them in your lectures. Or go to some CSEsoc events, they're quite active.

I think you should do 1917, but just make sure your committed and willing to work hard in it if you choose to do it. Don't go into it thinking you'll suffer, plenty and plenty of people have gone in with no programming experience absolutely fine. Keep up with the work and you'll be right. Keep in mind comp1917 is taught differently in sem1 vs sem2 (apparently).

Not on the spot I'm not. I'm not bothered under standard circumstances to do it at all, given how much of a WAM killer it can be.

And probably a bit too lazy to join the CSEsoc I guess...

I have heard good things about 2nd sem COMP1917, it seems to be less tedious as there isn't a "resume" part.

I get told mixed things about sem 2 being just as bad or better. Keeping the thoughts at the back of my head.

Also wam doesn't mean much. Idk why you're so worried about marks when you don't even want to make friends in a subject.

Seriously, I'd focus more on that rather than marks. Cause at the end of the day, your marks won't mean everything. This is not HSC anymore.

Because WAM means more to me in actuarial. If I had chosen computer science like I said back in post-HSC break things might've been different and getting experience would've had to take over. (Not that I'm gonna neglect experience... it just means I demand my balance to shift)

That and you know, I have to have good marks or I feel like shit...

(On the sarcasm note lol you'd probably get exemption from it if you transferred into UNSW...)

Re: MATH1131 help thread

Reality with "friends" is that I'm willing to do courses with people I know. Because that secures me a greater chance of us helping each other out.

Otherwise, I will follow the set plan https://www.maths.unsw.edu.au/sites/default/files/3589_2013.pdf
And do whatever I feel will bump up my grades


My brief interest in computing cascaded away very quickly. It's not something I'm into. So motivation without something pushing it is more of a dream than something I'm willing to produce myself.

Re: MATH1131 help thread

Just checking, is the parametric representation of this?

MATH1131 help thread

Just checking, is the parametric representation of this?

No, <0,0>+<0,1>t if 2 dimension

But if more ie 3 then

<0,0,0> + <0,1,0>t + <0,0,1>r

 

[turntaker]

Re: MATH1131 help thread

No, <0,0> + <0, 1>t

but can't we just leave out <0,0> cause its 0

 

[InteGrand]

Re: MATH1131 help thread

No, <0,0> + <0, 1>t

His one is fine. If it goes through the origin, don't need to include the (0,0) part (plus adding a zero vector to a vector doesn't change it, so you can leave it out).

Re: MATH1131 help thread

Yeah you can leave it out.

True...

Agreed. Leave it out if you want @TT

Do 1911 then, don't do 1917 if you don't like computing lol.

1911 is almost the same thing right?

Re: MATH1131 help thread

The question says:



Is the answer of:

<x,y,z> = <2,-2,5> + <1,1,-3>t (my answer)

the same as:

<x,y,z> = <1,1,-3> + <-2,2,-5>t (textbook answer)

No, they're not the same. The easiest way to see this is to observe that the two answers' direction vectors aren't parallel, so they represent different lines.

I think you basically mixed up where to put the parameter t / direction vector. The t is a scalar multiplying a direction vector, an example of which is a vector joining P and Q (so (-2,2,-5) is a direction vector).

Is the textbook right?

Yes, it's right. You essentially had the same two vectors as it but put the "t" with the wrong one.
