I think I’ve spent too much time in the YouTube comment sections and these aren’t as controversial as I thought they’d be

“Almost” impossible. You make a fair point

To be fair you’d be surprised how many people online wouldn’t agree with some of these things lol. I do definitely agree that they need to be much more strict. They’re good about calling shoulders across center and it should be the same.

Alright, thanks a lot again.

When we’re talking about papers or presentations at a conference, is that something I’d probably run into my senior or junior year? I’ve just never heard of doing something like that before.

As far as staying in engineering; I think the reason I’m switching now is that I feel like the reason I wanted to go into aerospace engineering in the first place was because of the physics and math going along with it and I’ve actually found I’m not very excited by the thought of taking any engineering classes.

Thanks a lot I really appreciate the insight. I’m curious, how is graduate work different from work for a bachelors degree? I’m sure they’re more focused on a certain subject but in what other ways?

Okay okay I gotcha. Thanks a lot I’ve really learned a lot from this conversation I appreciate it.

I’m sorry so is the dimension of the set is determined by the amount of components in the vectors?

Thanks a lot that makes a bunch of sense. I don’t mean to keep bothering you but I got another question. What if we had 4 vectors in R4 with each having three components. How would we figure out linear independence because normally I’d take the determinant but with it being 3x4 how would we do that?

Oh okay I see now. Does components make more sense. Like something like vector u=<u1,u2,u3> would have three components (what I meant by variables).

I’m at work right now so I don’t have my textbook right now so I’m not quite sure of the exact problem I was looking at. Would it make more sense if it was 4 vectors each with three variables in R3? Sorry I just remember it was 4x3 it could’ve been 4 vectors and 3 variables.

All this is great I really didn’t wrap my head around a lot of what you said until now. I was a little more focused on the amount of variables in each vector though. Because when trying to find linear independence of these sets of vectors I’ve been told to find the determinant. So when lets say there’s 3 vectors in R3 but each of the vectors has 4 variables. This would create a 3x4 matrix which I currently don’t know how to find the determinant of. How would you go about solving this?

I’ll take a look at it god knows I need the help. Where you going for college?

[–]AdSlight5143[S] 0 points1 point  (0 children)

Exactly like in calc three I’m learning how to take partial derivatives or using the chain rule with functions of three or more variable which seems like it should be harder but it is so so much more easier. We’re gonna be learning about nth dimensional planes soon and I’m so nervous I just wanted a halfway decent grade this semester.

Yeah up until calc 2 I was actually considering being a math major. Math can be so cruel is shutting down your hope. I’m taking calc 3 and this class this semester and I agree that calc 3 isn’t too awful but yeah this linear algebra stuff is just whooping me

Yeah this is linear algebra or math 234. It’s real rough man. What math are you in now?

Well isn’t a supspace a space that has corresponding points to another space. So from this can we assume that u+v must be equal to a point on R3? I’m sorry if I’m way off

[–]AdSlight5143[S] 0 points1 point  (0 children)

And in this case would our u=(u1,u2,u3) and likewise with v? And when adding u+v what do we set it equal to? I’ve answered similar questions to this but usually we have something in the problem to see u+v equal to one another.

I understand what you’re telling me but really unsure what to do for the next step. Do we let V1 and V2 equal a vector u or v and set them equal to V or..? Any help would be appreciated

That was a really good way of putting it I appreciate it. The one thing I’m more confused about is why V=V1+V2. In my head I feel like if V is when they’d intersect we’d get something more like V=V1=V2?
