Best ResponseYou've already chosen the best response.2or better yet...is Math important?

Best ResponseYou've already chosen the best response.0In one of the examples, I noticed that they made a quick substitution for the following vectors:\[\overrightarrow{i} = \langle 0,0,1\rangle\]\[\overrightarrow{j} = \langle 0,1,0\rangle\]\[\overrightarrow k = \langle0,0,1\rangle\]So are vector i, vector j and vector k defined vectors?

Best ResponseYou've already chosen the best response.2im thinking these are \(\hat i, \; \hat j, \; \hat k\) for some reason

Best ResponseYou've already chosen the best response.0Oh yes,\[\overrightarrow{i} = \langle1,0,0\rangle\]Sorry... messed up

lgbasallote

Best ResponseYou've already chosen the best response.2still thinking that's supposed to be \(\hat i\)

ParthKohli

Best ResponseYou've already chosen the best response.0OK, but is \(\hat{i}\) the same as \(\overrightarrow{i}\)?

Best ResponseYou've already chosen the best response.2\[\hat i = \; \text{positive xaxis}\]

Best ResponseYou've already chosen the best response.2and yes, i is defined as unit vector in x direction j is defined as unit vector in y direction k is defined as unit vector in z direction and denoted by i^ as said by lg

Best ResponseYou've already chosen the best response.2\[\vec i \implies \text{vector}\] \[\hat i \implies \text{vector component}\]

Best ResponseYou've already chosen the best response.0Yeah... @hartnn that's right!

Best ResponseYou've already chosen the best response.2think of it somehow like this: i => x j => y k => z

Best ResponseYou've already chosen the best response.2+ i => positive xaxis i => negative xaxis + j => positive yaxis  j => negative yaxos k => positive z axis k => negative zaxis

Best ResponseYou've already chosen the best response.2can u imagine a vector along xdirection and magnitude = 1.......thats idw:1347180055694:dw

lgbasallote

Best ResponseYou've already chosen the best response.2one more thing you should know, the expression for vectors is given as \[\vec A = x\hat i + y\hat j + z\hat k\] or something like that

lgbasallote
 3 years ago
Best ResponseYou've already chosen the best response.2that means i is a vector component for x j is a vector component for y k is a vector component for z

lgbasallote

Best ResponseYou've already chosen the best response.2so when you have \[\hat i\] that means \[\vec A = 1\hat i + 0\hat j + 0\hat k\] so there's no value for y or z so it just lies on +xaxiis

ParthKohli

Best ResponseYou've already chosen the best response.0Because I can't stand the fact that I can't answer so many questions on the site, and there are people like you who know a lot. :

Best ResponseYou've already chosen the best response.0I'm 13 lol, and I don't think that age makes a difference :)

UnkleRhaukus

Best ResponseYou've already chosen the best response.0the difference is 1 year

ParthKohli

Best ResponseYou've already chosen the best response.0I mean that age contributes nothing to how much a person knows...

lgbasallote

Best ResponseYou've already chosen the best response.0We evolved with certain rules that made no sense. For example: 1) Babies are supposed to play with toys. 2) Adults are supposed to watch movies with stripping scenes. 3) Kids don't know anything. I feel that it is *us* who evolved with these beliefs :) a baby can do calculus as well, but we made the baby play with toys.

Best ResponseYou've already chosen the best response.0An average baby doesn't have the necessary IQ to do calculus.

ParthKohli

Best ResponseYou've already chosen the best response.0WE MADE HIS IQ DOWN BY MAKING HIM PLAY WITH TOYS.

lgbasallote

Best ResponseYou've already chosen the best response.2to learn calculus you need to know algebra. to know algebra you need to know arithmetic. to know arithmetic you need to know kinesthetics

Best ResponseYou've already chosen the best response.2if your theory is right @ParthKohli then i can confidently concur that online schools educates people very well

lgbasallote
 3 years ago
Best ResponseYou've already chosen the best response.2online schools miseducate people because they keep jumping from topics to topics; skipping fundamentals

lgbasallote

Best ResponseYou've already chosen the best response.2that is also why you should not disturb the status quo

ParthKohli

Best ResponseYou've already chosen the best response.0I'm... not.... jumping, right?

lgbasallote

Best ResponseYou've already chosen the best response.2you are. you're trying to learn this without the necessary fundamentals

ParthKohli

Best ResponseYou've already chosen the best response.0Yeah, I am, but I didn't skip algebra... and I didn't skip logarithms... not even trigonometry.

ParthKohli

Best ResponseYou've already chosen the best response.0Thus, not leaving fundamentals.

Ishaan94

Best ResponseYou've already chosen the best response.0How much time did you spend on Algebra, Trig?

lgbasallote

Best ResponseYou've already chosen the best response.2however, you skipped topics

lgbasallote

Best ResponseYou've already chosen the best response.2there's a reason they give 4 years to algebra

Ishaan94

Best ResponseYou've already chosen the best response.0I would need a definitive answer.

ParthKohli

Best ResponseYou've already chosen the best response.0But I have managed to do it early... nothing's really wrong!

lgbasallote

Best ResponseYou've already chosen the best response.2it's not because people are slowlearners

Ishaan94

Best ResponseYou've already chosen the best response.0Parth I think you should spend your time more on Algebra and Trig. Calculus isn't tricky. IMO doesn't even asks question from calculus. Get a good book on Algebra and start solving it.

lgbasallote

Best ResponseYou've already chosen the best response.2honestly @Ishaan94 don't you think kohli could be a valedictorian if only he tried using the time he spends doing calculus to just master algebra? if he has this kind of knowledge on calc, then he must hve spent a lot of time, enough to have made him a valedictorian

lgbasallote

Best ResponseYou've already chosen the best response.2i think it's a false cause to study for OpenStudy rather than to study for academics

Ishaan94
 3 years ago
Best ResponseYou've already chosen the best response.0hmm I am not against Parth learning Calculus but the thing is Algebra could be a lot trickier than Calculus. So it's really important that one spends significant amount of time on Algebra. As for academics I don't think 8th grade is really complex. He could still be a valedictorian. :)

lgbasallote

Best ResponseYou've already chosen the best response.2he still has other subjects though. math is not everything

Best ResponseYou've already chosen the best response.0I might be wrong person to discuss about getting grades in school. I never really payed much attention to grades.
