Division in english

[Lillen]

In elementery school we were taught division. But because of my fathers death back then i couldn't focus so much on school. Before my father's death I was always ahead of everyone in math, but after I was the one who was about 100 questions after the others. I missed to whole idea of setting up things in division and solving division.

I have reached undergraduate level of math, but i am totally handicapped in division.

I need to go back to basics, and read wikipedia which latly have become harder for us groundpeople to understand.

They use a facual language I don't understand!!!

 

[Targ]

So if you used to be the best at maths in your class, then how come you only scored an IQ of 30?

 

[dewaddict84]

Who are groundpeople?

Why learn it in English and not your native tongue of Swedish?

If you want to learn the terminology used in mathmatical division, yeah, go read wikipedia. Unless you have any questions, I'm not sure what to do. Maybe some examples?
Like, 12 divided by 3 is 4. 15 over 4 is 3 with 3 remainder.

Also, Targ, ouch!

1 Math has nothing to do with IQ.
2. I mentioned before that according to a psychoanlytic i had the score of The analfase age devided with my real age multiplied with one hundred!
Cognitive speaking, those progressive matrix test mensa has, i scored close to mensa members.

To caluclate IQ you need to take the general age of the testscores outcome devided with your real age multiplied with one hundred. For instance, if you score as the general 12 year old when 10 your IQ will be 12/10*100 = 120

The psychoanalytic messured my IQ to 15-30
But the mensa test on the internet messured my IQ to 127 which is three points away from being a mensa.

When we are at it, i must reveal that I don't trust the way we messure intelligence because we need to know what to messure first, simplified, we don't know what intelligence is yet!

Other critics i can come up with against mensa tests or Progressive matrix test is that it has alot of similarities with a old witch formula that causes repetative thoughts. I believe that people doing these test learn to be repetative in notions, or trigger ideas that no one has a clue what they mean and repete them to everyone! You become locked into a pattern so to say!!

The critics i come for psychoanalytic ways of describing you IQ, ie the phase you are in. Is that somepeople get stuck in that fase because it triggers lustful feelings and thus gives positive reward for embody those behaviours. As an example a persons fixation with the gentitalia should have been over at the age of 7-8. If a person who is 30 years old still have fixation with his genitalia he will be diagnosed by the psychoanalytic as poorly gifted!

And finally common knowledge is not IQ according to psycholgists!!!

Looking from a humanistic view i am totally skilless. Since all i know to do, is typing on a machine, smoke ciggarettes that i roll by hand, and eat food. I can dishwash, and i can go to the groserystore to buy supplies, i can also bubble bubbles with a drinkingsstraw in diffrent fluids. The other things i can do involves illegal activity, and i have no need to break the law!

How do I split up and joint devision such as

x/y+x/z=?

 

[dewaddict84]

split up a joint division
Not "and".

As for the problem, that's, you know, arithmetic.
You can pull out the X so it's X(1/y+1/Z)
And a bunch of other stuff. But you don't just simply join four variables.

The IQ figure is reached by dividing something by something else.

Someone who isn't good at division won't necessarily get the usual sort of answer.


From what I've seen it is really only Americans who firmly believe in IQ anyway.

People in other countries instead of just claiming to have a high IQ and that they would do a really good job of learning things, just move on and actually do it.

 

[Lillen]

What i can do is derivive the derivate of a sine function halfways. I only read the conclusions in the book when we read about trigonometry. But i still lack the skill off division.

sin x = -cos x

Someone comlete the solution for the problem

 

[Lillen]

The criminal activities I know are alot. But i don't practice them because i have no need to break the law!

Sniff an IP number at a host computer in a network while the victim is surfing on the internet, Apply that IP number to my computer to become a part of the network and spook around there abit.

Bloody Christmas Carol, i even know how do do money loundery, but that is nothing i am involved with...

Name any topic, Mork will find a way to insult Americans.

Is English your first language?

sin x = -cos x

Someone comlete[complete] the solution for the problem

. . . wut?
Seriously? No... wait.... SERIOUSLY?

ok, first off, there is no problem. That's simply an equation.

Secondly, the equation is false. sin x does not equal -cos x. So anything I'd try to help you with is kinda moot. Did you get this out of a book? Did you mean sin y = -cos x?

Third, that's not a sine function. A sine function is something like y=sin x. That's THE sine function. There's an X and a Y. With those two variables you can graph out the possible values and get a wavy line.

Fourth, what the hell are you going on about in the next post?
No really, just where did that come from?
You can't sniff an IP address of just anyone, you have to have them connecting to a service you're running, like a website. That's not illegal. OR, I guess you could run some sort of man-in-the-middle attack. But really this sort of thing is for setting up a man-in-the-middle attack.

You can't simply set your IP to anything and receive traffic intended for someone else. You need to connect to the DNS and set your IP address there. Now, given that the DNS system has security holes, you could theoretically have been implying that you'd also gain control of the DNS that serves the target. That assumes you could find which they're using somehow. But from the rest of your post I doubt it.

And if you DO redirect traffic using an IP collision affair, you STILL won't have access to anything and won't be "part of the network". For that you have to hope that they log into something, and inspect the traffic for a password or something. But that will only grant you access to whatever service they were going to, and not their own computer.

So, long story short, you're a poser with no clue about what you're talking about. Get of the Internet and finish your math homework on your own.

We´ve had that already, didn´t we?

I don´t know about intelligence tests, but the inability to understand and correct your own mistakes when they have been explained to you is not a sign of high intelligence.

 

[Gracchus]

The IQ is determined by the answers to to a number of questions about general knowledge, and aptitudes. The mean score is assigned a value of 100. One standard deviation from the mean is fifteen IQ points. Adult"s tests are usually different and scored differently than children's tests.

Of course IQ, is a single score assigned to several skills.

I have one brother with a master's degree in physics, but he is somewhat shaky in the language arts. Another brother is good with words but stands in astonished befuddlement before simple trigonometry. As it happens, their IQ's are within five points of each other.

So which is smarter?

To have a high IQ simply means that you have a talent for scoring well on IQ tests.

And to respond to the OP, the best way to learn any mathematics skills is to work lots of problems, and have someone check your work.

 

[Lillen]

So you are saying that the derivate of sine x is not -cosine x?

Equation vs function, sorry for the misconception... it is easily made..

 

[Gracchus]

So you are saying that the derivate of sine x is not -cosine x?

The derivative of sine (x) is +cosine (x). The derivative of cosine (x) is -sine (x), and thus the derivative of -cosine (x) is sine (x). From this one can by the use of series differentiation one can determine the value of pi to any desired degree of precision.

Equation vs function, sorry for the misconception... it is easily made..

Just remember that f(x) is a function if for each value of x there is only one value of f(x).

As Gracchus said...

I really don´t understand why it is so difficult to check such simple facts, when you have the whole of the internet at your hand.

I know that I am bad at remembering formulas. But that is why I look up stuff like that before making explicite statements about them.

Knowing where to find the things that you don´t know is one of the first things I learned at university.

 

[Lillen]

It was the other way around... I will continue to read math, even though i feel that i forgotten basically everything i was taught in school. I am on course D (Trigonometry, differential equation and intergrals) in adult highschool (swedish KomVux, communal adult school were people above 20 can get a highschool diploma).

Something i will have trubble with is the evidence for a certain trigonometric equation. Prove that cos x = -sin x

The derivative of sine (x) is +cosine (x).

I remeber something else... but i could be wrong..."Cos x * Sin x" or somthing like that

Because the cosine x -curve is not the same as sine x -curve, it is cos x = sin x + 180... I think... Now i could do freodin a favor to check with sources before i utter mself... but that wont add anything in the conversation or will it?

 

[Lillen]

Oh got ya...

I see the point,

Again, this is only true for certain values of x.

If you want to prove that the derivative of cos x is -sin x, then you'd need to derive from first principles of differentiation.

This is probably unwarranted advice, but you should probably make it clearer in future whether you're referring to division or derivative, as they're quite different things - and you seem to be flitting randomly from one to the other.

I remeber something else... but i could be wrong..."Cos x * Sin x" or somthing like that

Cos x*Sin x = what? "Cos x*Sin x" isn't an equation to begin with.

Because the cosine x -curve is not the same as sine x -curve, it is cos x = sin x + 180... I think... Now i could do freodin a favor to check with sources before i utter mself... but that wont add anything in the discussion or will it?

90 degrees, not 180.

http://www.sosmath.com/trig/Trig5/trig5/trig5.html

But in essence yes, this is the only way to directly equate a sine and a cosine function to each other for any value of x, you need to account for the phase shift of 90 degrees.

To add, can you bake a nuke out of a pizza and mushroom? Russian artillity pieces...

Pizza, yumy..
