Pre-Calculus Lesson 4.1 part1

[vaccumenhancer439]

Wow so fucking genius fuck you old nigger you smart you opened my eyes to the door.

[MegaCheezyWeezy]

Im just using this video to fall asleep :(

[themathmaster]

@MegaCheezyWeezy Sweet Dreams!

My school is so lame, I am in integrated Alg. 2 instead of CP Alg 2(4 chapter difference) - but I have a high A in the class, and they won't let me move up to CP Analysis(Precalc) next year.

[themathmaster]

@ion5061

I teach Pre-Calculus online.

[ion5061]

@themathmaster How much does that cost?

[TrevorKingKwong]

Is there any practical purpose to comparing a function and its inverse, or are they only useful as separate functions to find a single result such as distance? For example, the only practical purpose I find for comparing the two functions is to compare slopes. So if x = time, and f(x) = distance, this means that according to your graph; the amount of distance covered over time [f(x)/x] is greater than the amount of time covered over the distance [x/f(x)], yes?

[glowingdarkmatter25]

i like, but I cannot see numbers very well...

[themathmaster]

@glowingdarkmatter25

You are right about the difficulty of seeing the numbers. It was one of my early videos and I had not gotten the hang of how to improve lighting. But I was excited about getting the lesson out on youtube because I thought it would help.

[glowingdarkmatter25]

@glowingdarkmatter25 okay will keep watching anyway. ;+)

[sugarcoated122]

@singerazboi100 no.. At my school it's algebra, geometry, algebra 2, precalc, AP calc Ab or Bc but I'll most likely take AB

[sugarcoated122]

hii!

im in geometry now but im planning to take algebra 2 over the summer so i can get to precalculus next year so i was just looking at these so i can get a good headstart. youre a good teacher!

[themathmaster]

@sugarcoated122 You are so welcome! Good luck!

[Singerazboi100]

@sugarcoated122 Dont you have to take trig before Cal?

[Ibeatyou23]

I doubt you'l read this because this video is so old lol, but what is the point of the inverse function. Why would it matter which one you used to find the other, could you not just graph it and find the x co-ordinate from the y co-ordinate or vice versa?

[Shakespeare1612]

@Ibeatyou23 Graphs can only be so accurate. There are many science and engineering applications where you need an answer accurate to say 6 or 8 places. Can you tell the difference between 2.23424321 and 2.23424325 on a graph? No, clearly not. Graphs are great to getting into the ballpark, but only algebra will put you across homeplate, right in the strike zone.

[themathmaster]

@Ibeatyou23 Yes, you can use a graph and find the x and y co-ordinates or vice versa. When we know how to find the equations for the inverse functions and the properties that go with those inverse functions we can work without needing to graph every equation we work with.

[wenaolong]

In life, some people start off really fast but then suddenly start to stall and then peter out for the rest of their lives. On the other hand, some people start of as if they were at the rear of the pack, then at some point they suddenly begin to accelerate seemingly to infinity. The first group of persons are, shall we say, cubic-functional in nature and the second group, shall we say, are comprised of those who could be called, shall we say, cube-root in nature.

[wenaolong]

@wenaolong oops, I mean the other way around. :P

[wamu2323]

damn. this guy knows how to make math boring.

[Shakespeare1612]

@wamu2323 Math, if you are really doing it, is inherently boring and cannot be made otherwise. Like mowing a lawn or washing a car. It's just hard work that needs to be done. We do it for the result, not because we can always enjoy the process.

[xwinterxfreezex]

im in geometry and ik what this guys tlkin bout holy shit o.O ima try n go up to the ap classes :D

[Josh1billion]

This dude's a really good teacher. Thanks for the help.

[mvang01]

wow this guy is good at teaching. my teacher just goes over one problem and sits back down and has us do the rest.

[hunterhalo2]

You are the best teacher of math I have listened to. Beautiful stuff man.

[cameroon37]

can some1 help me wit dis problem plz...find the area of the triangle formed by the line y=1/2 X +2

[wingegia]

that is very easy. just draw a graph of that linear equation. then form a right angle using the graph. usually you connect one point at the right of the line. try (3,6) and connected to (0,6) there you go you created a triangle! then use area of triangle theorem 1/2bh. answer turns out to be 9.

[XxsheepslayerxX]

the height would be 2 (y-intercept) and the base would be four (x-intercept) therefore 1/2*b*h=1/2*4*2=2*2=4 easy as pi. (get it?)

[O0oSorousho0O]

Ok what's the first, first lesson. It says 4.1 im confused

[whoaarr]

naice

[TATGemini]

Well explained I'm in precalc now and that's pretty clear!

[CAFEYHUMO]

Nicely explained, easy to understand, thank you.

[psengsouriya]

I cant see the board... man why always the asian gotta sit in the back of the class

[XXXBoBoXXX77]

well, u gotta ask them..

[rugersribshack]

:sadcam:

[Dabomb89104]

ahh the teacher is black

[PopaRocks]

So much better than my teacher!!!

[ishane84i]

soooooo good!

[jasonguyperson]

So this is what Jordy looks like without his neural implant....

J/K Math Master! I love your vids!

[mistorm]

be my math teacher.

[giggleblaggle]

i'm skippin' school today 'cause i don't wanna take a precalc test. i would be taking it right now if i were there

[bzboarder17]

easy as hell

[FarFromEquilibrium]

great help.. thanks, keep it up XD

[ahmad19526]

nice i in alabra and tryin to learn pre calculus and do even take this class , put this video is learn little

[remedy54]

You should take english too >_>

[albinolintel]

hahahahaha

[Th1rt3enBmx]

hahahahahahahahahahaha

[cagian1]

OWNED!!!!!!

[cagian1]

You got owned man.....

[SolidVictory]

I have to join in on this chain and say you got PWNED.

[jasonguyperson]

OwNeD

[pushplayent]

Nice Math Master.

[rax7]

great

[80amnesia]

maths don

[Naujdavid]

Thanks math master

[Wcoltd]

I wish I had this dude as my precalc teacher. You rule MathMaster!

[lazypuddycat]

reminds me of math class.. I wish I had better math teachers in high school *cringes*
