But you do have to do more um
15,082
524
[]
volunteer
computations
15,082
525
[]
student
right
15,082
526
[]
volunteer
You know, I'm trying to think of
15,082
527
[]
volunteer
what would you say, knowing what you know now, what would you say
15,082
528
[]
volunteer
is the difference or hm how do I say this?
15,082
529
[]
volunteer
or how do I ask this
15,082
530
[]
volunteer
No, I guess, I just be kind of, what kind of summary would you say between these two methods? Like what's the purpose of substitution method.
15,082
531
[]
volunteer
Um, what's the purpose of
15,082
532
[]
volunteer
the partial fraction decomposition.
15,082
533
[]
volunteer
you know, why are um
15,082
534
[]
volunteer
why do we need them
15,082
535
[]
volunteer
What's the
15,082
536
[]
volunteer
the purpose of the methodology.
15,082
537
[]
volunteer
I know it's kind of a loaded question.
15,082
538
[]
volunteer
but I just kind of want you thinking like
15,082
539
[]
volunteer
you know, what's, you know, why are we even bothering?
15,082
540
[]
student
for every method we discussed
15,082
541
[]
volunteer
And why are we using these methods versus some other
15,082
542
[]
volunteer
imaginary method that we haven't thought of.
15,082
543
[]
volunteer
Maybe not for every method we discuss, just kind of in general.
15,082
544
[]
volunteer
I just wanted to kind of have you conceptualize and crystallize
15,082
545
[]
volunteer
your thought processes regarding these um
15,082
546
[]
volunteer
methodologies
15,082
547
[]
volunteer
so that you know kind of like, not only when to use them, but why.
15,082
548
[]
volunteer
and which method
15,082
549
[]
volunteer
you know, over another, cause you may have
15,082
550
[]
volunteer
problems that um
15,082
551
[]
volunteer
kind of overlap
15,082
552
[]
volunteer
and you can use one over the other.
15,082
553
[]
volunteer
And it, it might come down to preference, but you could also have um
15,082
554
[]
volunteer
you know, you want the solution of a certain form.
15,082
555
[]
volunteer
So you would use one over the other and just kind of like when, like why and when would you do that?
15,082
556
[]
volunteer
I know this is a, this is a lot to ask. Um, if you don't feel comfortable answering, just, just kind of be like uh.
15,082
557
[]
volunteer
and just say, you know, because they tell me to, but I just wanted you to um
15,082
558
[]
volunteer
kind of think critically
15,082
559
[]
volunteer
about these methods
15,082
560
[]
volunteer
and, you know, the rationale behind them.
15,082
561
[]
student
okay, lemme think
15,082
562
[]
volunteer
Of course, take all the time you need
15,082
563
[]
student
it depends upon the question. there can be multiple way to solve a prob, i'll go for the shorter one
15,082
564
[]
volunteer
True.
15,082
565
[]
volunteer
It's very pragmatic
15,082
566
[]
student
yeah, i need a quick way for exam.
15,082
567
[]
volunteer
True
15,082
568
[]
volunteer
Right, for your needs, yeah.
15,082
569
[]
volunteer
OK. Well, we got that out the way.
15,082
570
[]
volunteer
So we can move on to
15,082
571
[]
volunteer
for example 12
15,082
572
[]
volunteer
Unless you have more to say
15,082
573
[]
student
that was it? i thought it was like a conceptual like "why would you" question
15,082
574
[]
volunteer
I mean
15,082
575
[]
volunteer
it was
15,082
576
[]
volunteer
but then I realized that you're um
15,082
577
[]
volunteer
you're more only doing this because you have to.
15,082
578
[]
volunteer
Um
15,082
579
[]
volunteer
but it was like
15,082
580
[]
volunteer
I was thinking more along the lines of like
15,082
581
[]
volunteer
substitution method.
15,082
582
[]
volunteer
is
15,082
583
[]
volunteer
a way of
15,082
584
[]
volunteer
defining what we don't know.
15,082
585
[]
volunteer
right
15,082
586
[]
volunteer
Where
15,082
587
[]
volunteer
if we see something, if we can redefine it.
15,082
588
[]
volunteer
right, the in a grant, the, the integral, if we can re redefine it as something we know.
15,082
589
[]
volunteer
or an expression we know, then this allows us to
15,082
590
[]
volunteer
work with, work with it
15,082
591
[]
volunteer
because we, we've turned, we've turned unknowns into knowns.
15,082
592
[]
volunteer
right? And it's essentially like
15,082
593
[]
volunteer
dissecting it, dissecting the problem by looking at it, by kind of forcing it through a different lens.
15,082
594
[]
volunteer
and this allows us to work with it.
15,082
595
[]
volunteer
um,
15,082
596
[]
volunteer
where previously it was unworkable.
15,082
597
[]
volunteer
right? But the reason why we're using substitution method is because the, we can't integrate normally.
15,082
598
[]
volunteer
We take in something that's kind of unworkable, and we've turned it into something
15,082
599
[]
volunteer
um
15,082
600
[]
volunteer
just by looking at it differently.
15,082
601
[]
volunteer
rewriting the expression, right, the expression itself hasn't the problem itself hasn't changed. All we're doing is changing how we're looking at it.
15,082
602
[]
volunteer
right? We're redefining the problem.
15,082
603
[]
volunteer
and working it and working it that way.
15,082
604
[]
volunteer
versus um
15,082
605
[]
volunteer
you know, partial fracture decomposition.
15,082
606
[]
volunteer
where
15,082
607
[]
volunteer
you have this expression that you know all about
15,082
608
[]
volunteer
um
15,082
609
[]
volunteer
thanks to all the work we did and uh pre-calc, you know, that there's asintose, there's this, there's that.
15,082
610
[]
volunteer
Um
15,082
611
[]
volunteer
but then, you know, how does that relate to integration, it's like how do you find
15,082
612
[]
volunteer
Now, what does the area under the curve mean and all that. Um, we'll say, well, we can
15,082
613
[]
volunteer
redefine this
15,082
614
[]
volunteer
If we can divide it all out.
15,082
615
[]
volunteer
right? We've taken this
15,082
616
[]
volunteer
proper function. We've taken this function and turned it into like a
15,082
617
[]
volunteer
a proper function
15,082
618
[]
volunteer
right, which seems kind of silly that we, we've done all this in like algebra.
15,082
619
[]
volunteer
and done this sort of
15,082
620
[]
volunteer
silly methodology
15,082
621
[]
volunteer
and we get something that's actually workable.
15,082
622
[]
volunteer
Um, surprisingly, almost.
15,082
