34/60 looks better than 0.57

^ Your method looks more easily understandable than mine though .

Equations.

sin^2x-sin2x=3cos^x

5sin^2x-3sinxcosx-2cos^2x=0


Thanks in advance!

 

[Miwi]

I made a mistake.
1.) sin² x - sin2x =3cos² x

 

[Chaky]

I made a mistake.
1.) sin² x - sin2x =3cos² x

Ewww!

Okay both of your questions actually have a similar solution.

Use the trig identity sin2x = 2 sin x cos x and substitute it in. Also rearrange the equation so all the terms are on one side.

sin² x - 2 sin x cos x - 3cos² x = 0

What you have is a quadratic equation which you can factorise. That's the tough bit!

 

[Chaky]

Just start by writing out both brackets and then trying to slot the numbers in front:

( ..sin x + ..cos x)( ..sin x + ..cos x) = 0

It shouldn't be too hard to reach:

(sin x + cos x)(sin x - 3 cos x) = 0

 

[Chaky]

The solutions to the equation make each bracket zero:

sin x = -cos x => tan x = -1

and

sin x = 3 cos x => tan x = 3

Your other question is exactly the same method but a bit easier because you don't have to do a substitution at the start. It's ready to factorise.

woah you guys are math geniouses.

Barbie ads/Editorials

Hi Guys,
I am currently working on a school assignment with the topic real life dolls and I need some inspiration. Can you please post some editorials/ad/fashion pictures that remind you of barbie dolls?? Thanks a lot in advance!!

 

[Chaky]

sin² x - 2 sin x cos x - 3cos² x = 0

Thinking about it, you should just divide by cos² x at this point to get:

tan² x - 2tan x - 3 = 0

so you are just solving a simple quadratic equation for tan x. Same for the other question. It's been a while since I've done this!

^^Thank you so much! I figured it out later.
Karma!
Well, it wasn't very useful, the test was so difficult that I wrote only 28%.

Can shieben be used to describe the shift of production from one place to another?

i.e. Die Firma hat die Herstellung des Computers nach Indien geschoben.

Thank you!

Can shieben be used to describe the shift of production from one place to another?

i.e. Die Firma hat die Herstellung des Computers nach Indien geschoben.

Thank you!

So you mean the production has been moved from some place to India?

To express that, schieben isn't the correct word. It's a good example for the evil tricks dictionaries can sometimes play to you, though. People often find translations for words in dictionaries, but often not all the exceptions and phrases you use these words in are written in it. So you take the best translation out of them which can cause the 'problem' that sentences that make perfect sense in English have no point in German anymore.
I'm positively surprised you're giving it a try. The german, I mean. It's definitely not an easy language to learn for a foreigner. The other way round it's not as difficult.

I gotta mention, however, that what you've written there isn't complete nonsense. If you'd say that to a German, everyone would know what you're talking about. It's just that noone uses the word schieben to express a procution being moved.

In this case you rather say: Die Firma hat die Herstellung des Computers nach Indien verlegt.

Infinitive of verlegt is etw. verlegen. This can have several meanings:

1.) to lose/misplace sth
2.) to publish sth (e.g. book)
3.) to postpone sth./to reschedule sth. (e.g. appoinment)
4.) to lay sth. (flooring)
5.) to pass/reposition/install/run/take sth. (tech.)
6.) to resort to sth./to take sth. up (germ.: sich auf etw. verlegen)
7.) to be at a loss for (germ.: um etw. verlegen sein)
8.) to be embarrassed/shyly/sheepish/bashful/confused (germ.: verlegen sein) (or nonplussing = jdn. verlegen machen)

What you mean is 9.) to transfer sth./ to change position/ to shift sth.

Hope that helps. B) Good luck.

Fashion Houses based in NY???

I'm doing this research thing for my entrepreneurship class. Can you guys list the ones that are based in NY? Doesn't matter if it's high fashion or the lower more affordable ones. Thanks!

 

[MissMagAddict]

Well that would be quite a list...and since this is for a school project...shouldn't you be doing the work yourself? This is simple to find if you just use google.

 

[young_princess]

well I'm not asking for ALL of them. I tried checking out the websites of the brands I like but some of it is tricky such as companies that are originally from abroad like LV, Chanel, Prada. And I'm not in a fashion school I'm in business school. The examples are NOT the project themselves, I am merely looking for examples to mention in my project. I would really appreciate it if some other people in this forum could mention a few. Thanks!

 

[yourbestfriend]

Did you think about american designers? Calvin Klein, Michael Kors, Vera Wang....Donna Karan?

 

[young_princess]

I don't really like those brands, except for Vera Wang. So basically how do you find out if they have corporate offices in NYC? coz Chanel does right? I mean how do you find out this info through google? So that "I'd be doing it myself"
