please forget about that picture
it will confuse the hell out of you, and its not a very good representation of the graphs.

What graphs? The picture is a line drawing of a roller coaster.

@sarah-eats-cupcakes
Fair enough. I just think it's misleading to say the picture was bad representation. The drawing was meant to be simple in order to test one's knowledge. I do agree it may be helpful to draw individual graphs of each term in order to answer the question.

Centrifugal force. No such thing exists.

Errr... http://en.wikipedia.org/wiki/Centrifugal_force

http://www.physicsclassroom.com/Class/circles/U6L1d.cfm

Centrifugal force doesn't officially exist... well it does but not in the way most people think it means (it's called inertia because there is no force).
If enough people call it "centrifugal force", then that is what it's called (doesn't change the theory, only the name).

If enough people were to call a toilet 'the john', then that word would become synonymous to 'toilet'.
True, it would be easier if people would stick with the 'original' words, but this is how a language evolves (sometimes for the better, sometimes for the worse).

Inertia is the resistance an object has to a change in it's state (whether that be in motion or at rest)
Whereas Centrifugual force just represents the effects of inertia. 'Sarah-eats-cupcakes' is right, Centrifugal force is real and classed as a pseudo force.

...I don't need anything about graphs. It's a picture/drawing/design of a roller coaster, not graphs of the actual terms. lol But thank you everyone! I think the right answer is indeed free fall because true free fall is when there's only the force of gravity acting on it (towards the center of the Earth), which is not true in the picture.

Just a little guess, it might be I am misunderstanding the word friction here...
Wouldn't it apply to the whole graph instead of just that one spot?
If this drawing was only in theoretical form wouldn't it ignore friction? Free fall might not be so wrong after all then..
Otherwise, gravitation should be gravitation minus friction too for example.

This is what I think about when I hear friction..

i know
but if you draw seperate graphs for each stage you will find that you're ignoring alot of things(air resistance,friction etc) like @0sirt said

Quote from sarah-eats-cupcakes

actually, Centrifugal force does exist.
...nothing is pushing you outward...

Well done.

i asked my mechanics teacher about this and he said that centrifugal force does exist.when astronauts are trained, they spin them around in circles, the force that is pushing them back to the chair is centrifugal force.

They're just examples of where each term is. For example, there are more places where kinetic energy is at, but only labeled at the first hill.

Okay, so anyone who likes physics...come 'ere!

Okay, so here's a roller coaster display with various terms. Which one is incorrect and why? @_@ And for the right side of the roller coaster (my own question), is that a hill or is it just a turn? I have no clue. :'(
I'm thinking it's the free fall one, but then again, I don't know. So if anyone can help me out soon, thanks. xD

oh i just remembered something
free fall is supposed to take place in vacuum
air resistance is neglected
so its definitely incorrect

I'm supposed to write an essay for my British Literature class on anything we want that is within the subject of British Literature and when my professor asked me what I was doing my paper on I hadn't picked a topic yet so I flipped to a random page in my Norton Anthology textbook and it was George Orwell's "Shooting an Elephant" and so I just... randomly picked it to do my paper on (I do like the essay though)... It's supposed to be a paper with a debatable argument and in high school I just wrote analysis essays so I don't know what to write about... because anything I glean is analysis that isn't very debatable, I mean it kind of is but not something many people argue about, like the imagery and pacing emphasizes the suffering of the elephant... For people who are used to writing college papers or essays like this, can you help me? Please?

I'm not sure if this helps but I had to write debate essays for high school. Um I did a little bit of research on the topic you're writing about...apparently "Shooting an Elephant" is a comparison or metaphor to to British Imperialism in Burma. To make a debate, you could try to persuade someone to view British Imperialism/Imperialism as Negative or postitive. You like choosing a particular side to convince someone. For example, Imperialism despite its luxuries (money, land, etc.), has often left the countries that were taking over in ruin. Base off your thesis, you can use characters, quotes, and events in the novel to prove or persuade others that imperialism is wrong or beneficial. Although you're probably have a better time providing information for the negative side. Just saying. Well I hope this help... sorry if did not. 😃

Every argumentative essay is supposed to have a proper thesis statement (in which you give an opinion opposite to yours and a really short summary of the arguments you intend to use to refute that opinion), arguments that support your thesis statement (in the order you mentioned them in the thesis statement), and a conclusion in which you re-evaluate your argument.

A good thesis statement usually follows this kind of pattern: "Although some people argue that (opposing opinion), this is not the case because, (argument1), (argument2), ....".

Do you have a Wadsworth Handbook or something similar? If you do, that book also gives detailed instructions about essay writing and how to write a proper thesis statement.

I do know how to write a general thesis for an analysis essay and I know that usually the basic idea of an argumentative essay's thesis is "I want to convince (audience) that although some people argue (opposing opinion) however (opinion) is true because (point a, point b... etc.)" And all that jazz, I'm just not sure how to argue about something that seems like just analysis to me if many people already hold that opinion. My teacher says she wants something debatable and interesting... O_O

Compute this integral: ∫dx/(1+sinx)

my answer is tanx - 1/cosx + C
i don't understand why it's wrong 🤢

The same problem was on my last calculus test!

Basically, you have [integral]1/(1+sinx) dx
Then you separate that into [integral]1/1 + [integral]1/sinx (which is cscx)
You know that the integral of 1 is x, so you just have to add that on to the integral of cscx. That can be found be multiplying (cscx+cotx)/(cscx+cotx), and using substitution, you will eventually get ln(cscx+cotx) + C.
Then, the answer is x + ln(cscx+cotx) + C

I might be wrong on what's inside the ln, so just use substitution to check if you want.

Fractions don't work that way.
