The return of the "How are you today?" thread

[PsycRoxXptic]

Maths .. I don't have this subject anymore at school yay!

 

[jmbullet]

I feel fucking bad right now

it only works for ² and ³ though

and those problems are solved when you split the numbers and the powers of ten, like this, and remembering that you can only add numbers together when they multiply 10 to the same power:

(46.15 + 183.035)(7.14*10^-7)/(8.12*10^-3 + 7.77*10^5)=

(46.15*7.14*10^-7 + 183.035*7.14*10^-7)/(8.12*10^-3*10^8*10^-8 + 7.77*10^5)

the red thing is actually 1, so i can multiply stuff by it and it won't change a thing

so

(46.15*7.14*10^-7 + 183.035*7.14*10^-7)/((8.12*10^-8)*10^5 + 7.77*10^5)
=
(46.15*7.14*10^-7 + 183.035*7.14*10^-7)/((0.0000000812)*10^5 + 7.77*10^5)
=
(46.15*7.14*10^-7 + 183.035*7.14*10^-7)/((7.7700000812)*10^5)

now the top part....it already has equal powers so I just have to calculate the expression's value.

(46.15*7.14*10^-7 + 183.035*7.14*10^-7)/(7.7700000812*10^5)

=

(329.511*10^-7 + 1306.8699*10^-7)/(7.7700000812*10^5)

=
1636.3809*10^-7/(7.7700000812*10^5)

Now just divide the powers of 10 and the numbers.

1636.3809*10^-7/(7.7700000812*10^5)
=
210.60243023154217055325299241646*10^-7*10^-5
=
210.60243023154217055325299241646*10^-12

=
2.1060243023154217055325299241646*10^-10

=~2.11*10^-10

Piece of piss

And actually, when you sum up two numbers with very different greatness orders (like 10^5 and 10^-3) you may consider the smallest one as zero.

Happy wanking.

WTF

 

[Söy]

math makes me want to wank too...


not really

 

[vikk]

at cliff

 

[Sock puppet]

freaked out....our substitute bus driver almost ran into a garbage truck

 

[Nikki]

I feel somewhat ok. Sick,nearly passed out in school on monday,finally got some sleep today,still feel sick,though

you're a math-fanatic right ?

 

[vikk]

you're a math-fanatic right ?

yes

 

[PsycRoxXptic]

I'm afraid to go at my college today ....

 

[hatecrewchick]

have to be at school at 6pm"

 

[PsycRoxXptic]

Me at 12:10 but I will take the bus at 11:20. I finish school at 6:00 today arghh

 

[MegustaMucho]

*HUGS*

 

[Roel]

lol, leandro is oldschoolmath god
I'd use my calculator for it My math is alot different than this stuff tho, learn methods so we can use them for other, useful classes.

 

[Leandro]

So is mine, that doesn't count as maths It's just stuff we use all the time in physics so I'm quite acquainted with it.

I'm actually learning calculus involving functions with multiple variables(triple integrals are dah shisnitzz), linear algebra, and some stuff about diferential equations...

 

[Roel]

Yea same here. I'm done with lineair algebra, which proved it's use in calculating forces etc. I've had a course on differential equations aswell, but failed the it last year I'm gonna be using those alot aswell tho I'm afraid. Using Fourier stuff now aswell, that's the part I do understand, it's easy I'm having my fourth course calculus now aswell, passed the first 3, now we've had 2 weeks of the 4th part and finished triple integrals and all the nonsense aswell. You happen to use the book called "Calculus" aswell?

 

[MIMA]

today was soo fuckin boring

 

[Veronika275]

Today was ok.

 

[Nikki]

I'm feeling fantastic

 

[Sock puppet]

my whole left arm hurts, i just got a tetnus shot and blood withdrawl on it
