College Algebra - Lecture 3 - The powers that be-Exponents

[puppychuu]

who teaches algebra in college? im in friggen 8th grade, not even in the advanced math course, tryin to get in and i learned this already. i mean i get that some people dont know math as an adult but you dont have to go to friggen college for algebra.

[2eelShmeal]

@puppychuu lol... Dude... it's Missouri. hahaha Give 'em credit....

I shouldn't talk. I'm from Jersey. he he

That's good shit brah... You pimping the variables out like that? Oh snap.

[puppychuu]

@2eelShmeal im also from jersey lol, but in a suburb near new york. and jersey is pretty cool, it got rutgers and princeton

[2eelShmeal]

@puppychuu Are you Boriqua by any chance with a name like that? lol

[puppychuu]

@2eelShmeal no...

[2eelShmeal]

@puppychuu lolol I know it was odd right? Just a shot in the dark. It's all good.

This professor moves fast right? Have you made it past lesson 5 or 6 yet... or do you even intend to? I'm sure it'll get more challenging for you if you hang in there. Then again, what do I know?

I'm 40. Just turned it last week. I too remember a LOT of this shit.. And I learned it back in the 80's... hahaha I never made it past Algebra 2 though, so I'm sure it'll get much tougher... for me, anyway. =) Peace.

@92Payka you're saying "wow" because you're either brainwashed, or can't think for yourself. in general, the "negative times negative" rule could pretty much go either way. it just took one douchebag to say "let's just make the tougher of the two to comprehend, the standard".

[ThedudeVip3r1990]

God Bless you Sir!

[Onedarkandwindynight]

Very clearly presented and a logical flow - Well worth watching.

[manq211]

Don't confuse 0 power with degrees, LOL

[TheMadFlea]

Is there a book that follows along with the videos?

[Juan58010]

i bet this guy gets pussy every night!

[powerhousephg]

that negative times a negative rule is horse shit. so if i lose a bet with someone, i can just set up a "double or nothing", and lose on purpose to get my money back? lol....yea...ok

[FullWaveElectronics]

@powerhousephg That would be a negative plus a negative.

[5w33ti3]

@powerhousephg "Double or nothing" works. If you lost once, that's -$10. If you lose the double or nothing, then you have 2 x -$10 = -$20.

@TheoryIsSpeculation I don't know what course you have taken or what you do.But trust me, Exponents & logarithms matter a LOT in every field.So if you don't have time or motivation for the whole series...here's what I will suggest for you -"Lectures-3,28,29,30,31".That will cover all of exponentiation & logarithms and it will take a week AT MOST.If you got more questions feel free to ask.(I got immense help from those who finished before me & would be glad to help others

[oclaros1]

Wonderful! I am learning algebra for the first time since high school. Wish I would have had this when I was taking it 20 years ago.

[DaViDsMoMmA11]

YOU ARE THE MAN!!!! I love watching your tutorials!!!

[frezneck]

this is better then supervised lessons.

[oramrj]

Maybe have not seen the previous lessons, he explained it very well in great detail.

[jakelongg14]

0:44:37 / 1:32:36

[omniscientken]

so what does he mean by rational being repeating decimals and the irrational being non repeating decimals?

I'm still a bit confused because isn't 1/2 non repeating (well the 0s are repeating) does he mean the non 0 ones are irrational?

[bangalorebully]

@omniscientken It's Ok to be frank about your confusion.Let me try to explain (It's simple you see)

--In the decimal form of rational numbers,after the decimal point either a sequence of digits get repeated (.25252525.....), or after a particular sequence of digits ,another digit starts repeating (.1652222222.....).

--In 1/2 as you have asked, the repeating digit is "0" (.500000..)

---But in irrational numbers there is no repeating pattern,the digits are just random.Eg."Pi"

I hope that helped!!

[omniscientken]

@bangalorebully yeah that did help a lot. Thanks

[veronicamelover]

good lecture !

[MrQUIET54321]

omg he looks like my math teacher :O

[anabolicErik]

aw, here we go, finally getting into the nitty gritty of things on this one :D

[cageybee777]

Thank you, thank you, thank you...infinity :)

[rasikanihani]

We have thousands of profiles about girls naneedj.info

[surajzdev]

very nicely explained

[SNROPQUEYR]

Prof Delaware is absolute in his explanation of Math. If all teachers around the world where to this standard, the budding population would be a far better place to live.

[arsenalfooty4]

I think he meant "to the something root" not "power" @ 1:02:42

[kkonstantinosss2]

Two words, good job! isn't it four words, oh no, it is nine, Do I have it under control? ....-No-.... END OF LINE

[KRSchannel]

example is not written, ex. its e.g.

[monrenaissance]

@KRSchannel e.g. is just an abbreviation for a latin term meaning exempli gratia which means "for example". It seems circuitous to write an abbreviation for a latin phrase when you can just shorten the english word and mean the same thing.

[monrenaissance]

Handy Lemma, or Hand Delimma? Bum bum bum!

[costantr]

Could anyone tell me what textbook was used for this class or what book could be used to study this material along with the lectures? Richard does a terrific job of explaining the material. Thanks, costantr

[somcool1]

@costantr, College Algebra Enhanced with Graphic utilities by Michael Sullivan. This is the one which is prescribed in the course website.

[davidtamuna1]

I really wish my teacher would be so good as you :) I cant speack english well because i am from georgia but, i understood everything what you explained : )

thank you so much ::) for this amazing work

[DragonBruceLee27]

WOW THNX A LOT, NOW IM GONNA ACE THAT TEST

[dorsalwhistle]

mathematics is a series of tubes!

[djbarcode5xyz]

NOTE TO SELF: Stopping at 12:34

[AEVautomatic]

wow even people who can do advanced multvariable calculus with ease have no fucking idea what he is talking about. 5 times box is box box box. Wtf

[Worteltaart]

@AEVautomatic : Would it be different if he was to say 'x' instead of 'box'? And if so, why?

[tashifalex]

thank you! helps me prepare by myself!

[ymacee]

Prof: Richard Delaware, you are the type of person the world need. Your gift is golden, and priceless because you are teaching thousands people every minute. This society should reward teachers, and professors better than politicians & CEOs. God will reward your work some way.

[hiteshswami]

wow.... i never seen such a beautiful way to explain the negative exponents.....full marks

[NFLmanic]

i am so laughing right now!!! i europe we learnd this in 8th grade of primar school! XDDDDDDD

[tekxtinct]

@NFLmanic

That's why you're still dumb

[HarrisonGoblin18]

Most people do... I learned this in 8th grade public school in Arkansas

[chriscougar86]

@HarrisonGoblin18 I know what you mean, i did this in middle school in Indiana/oklahoma. i was trying to relearn for before i started college.( been outa highchool for a while) things are harder now than they where in the 90's, which i think these videos where from the 90's. lol.

[Faelsun]

Heres the funny thing, I went to two school districts growing up, Nashville and Mississippi, in MS they dont teach you this stuff until you get into the advanced math your senior year of High school, they teach it in 7th grade in Tennessee.

[chriscougar86]

@Faelsun I thought i did ok in math in school, but i went to take a college placement test and was surprise at how much more complicated it was. i graduated in 06. things change 4 years i guess. I slept allot since then too.

[EV150]

@NFLmanic - is that why your biggest oil corporation was too stupid to bother doing a simple test that's been used for decades and now we've got the biggest ecological disaster in history on our hands?

[Faelsun]

Its ok jokes on him, the British are already working out how to get the taxpayers to Bail out BP.

[suomie1984]

that's very very helpful for me! Prof. Richard Delaware is the first person in my life who can explain mathematics to me!

[llewgnal]

Wow,,, Click

 This is real high speed learning...

Thanx

[schulzecdz]

Keep getting missing file message.

[rhettrobinson]

"We've discussed nothing." *rim shot*

Good stuff; just getting started on these, but these are really nice - clear instruction, repeated examples and a sprinkling of dry math humor every now and then. These are presented better than my "real" class to begin with, and can be reviewed until I get it.

Richard - You're the man!

These videos offered by UMKC are jewels! The original encoding for these prior to uploading should be better, however... but it's at least visible.

[thinker6236]

Now so many things in mathmatic makes sence, God bless this man .

[SHabeha]

he wasted so much paper which he could have just wrote on the back of them......

[chizzeee]

@SHabeha i think he should just have use white board. since he got loads of ink on that pen as he has so much paper. :)

[stephank]

this man should be paid to draw lines

Actually, 0^0 is 1.

"As a rule of thumb, one can say that 0^0 = 1 , but 0.0^(0.0) is undefined, meaning that when approaching from a different direction there is no clearly predetermined value to assign to 0.0^(0.0) ; but Kahan has argued that 0.0^(0.0) should be 1, because if f(x), g(x) --> 0 as x approaches some limit, and f(x) and g(x) are analytic functions, then f(x)^g(x) --> 1."

[BigCrazyDude2343]

Men you are saying that 0 to the 0 power is in-determinant? And we can use L hopital rule to say that it equals 1?

[Duralm]

Im doing this in junior high school o.O

[Omega231984]

very detailed, I thought the greater than side was the open side, I tried telling my former college teacher this
