Credit default swaps? Theyre complex — and scary! The receipt you get when you pre-order your Thanksgiving turkey? Not so a lot. But they have a lot in typical: Theyre both derivatives. Senior Editor Paddy Hirsch explains.

please come teach at Rutgers and replace my calculus teacher.. he’s as competent to teach as a squished cricket.
He made calculus like a joke, good job mr. Khan.
Good supplement to lectures especially for pre-test review. Thanks
@cml4456 Really?
I like my professors at my college!
They show us a quick proof and then practical ways to solve our current problem.
i can now catch up with my AP Calc AB class. Thank You.
Fantastic video!
Though less descriptive than the “New HD series”, this video provides that “Eureka” moment, where math all of a sudden becomes fascinating. You’re videos are great, but the new HD ones lack that moment.
@xBrodyt3x Thanks but i think i got it . My answer is 2x – x^3 / ( 1-x^2 )^3/2 Correct me if i’m wrong.
@leoqaz003 Math is rusty, dont take this as accurate but i think it’s 2/rootx – 2x
Find the derivative of x^2 / √1-x^2 ? PLs help I need to know
I was wondering whether there’s any video on derivatives of trigonometric functions from calculus 1 by khan academy? I tried to look for it, but couldn’t find it. I would really appreciate it if someone could post the link here. Thank you!

@strikemewiththunder yeah, math videos on youtube is soooo helpfull! But, just wondering, do you really have to pay for university where you from?
Power rule is so much easier…
why can’t you just be my teacher. xD
i understand derivitives! thank you so much!!
‘
Quiz tomorrow…this is helping so much!
YOU ARE THE ANSWER TO ALL MY PROBLEMSSSSSSSSSSSSS IN THE %UCKED UP WORLD OF CAlCULUS!!! many thanks!
I know a lot of ppl say thanks. But i’ll say it too: THANKSSS!!
Thank you so much. I couldn’t understand anything my teacher was saying when he taught us that, but you really cleared it up for me.

2:52-3:30 – in physics that’s known as ‘instantaneous’. Right?
Ur better than my math teacher
@strikemewiththunder HELL YEAH !!!
Why do my professors have to make derivatives seem more complicated than they need to be? When Khan explains it, it seems so simple!
IT MAKES SO MUCH SENSE NOW!
Wrong. Futures and options are not derivatives, because those contracts have deliverable assets with intrinsic value. A real derivative has no intrinsic value. A real derivative contract has no intrinsic value…it’s price is based on the underlying commodity ,stock, interest rate. ..and so on …nothing more. Contract expires buyer or seller do not exchange nothing. A derivative is basically a gambling instrument based on only price. They are not legally traded, nor regulated.
boring!
What school did you go to, and what degree/education do you have?
-A
very easy to understand and a clear example! thanks!!!
and hence fractional reserve banking is just betting with other people’s money and possibly losing other people’s money.
Great lecture…thanx.i now understand the concepts…
Love the pen throw.
Thank you, that makes perfect sense, however, can you now explain why all of these things might fail all at once and thus create an economic catastophe that everyone says is coming. Because apparently derivatives ARE based on some real underlying good, so why would they all fail at the same time? If they are based on interest rates or an assumption that housing will always gain in value or that markets wll always go up & then they don’t, then that makes sense.
complex derivatives = CDOs = Goldman Sachs’ taking advantage of AIG’s insurance of failing CDOs = corrupt, ruthless, investment company
@mooeythemooseman did i say it did?

Protip: IQ is just a correlation of intelligence.
Being in Mensa doesn’t automatically garentee a win in everything you do.
@danndan6 Are you actually a member of Mensa?
Awesome video, thank you! One question.
So assuming massive corporations are buying ‘Bets’ that oil will be worth more say next year? It becomes a supply and demand thing, deman goes up, value goes up, you made a good bet. So then it could be in some big corporations best interest to keep climate change and peak oil under wraps until the date is up on their Derivatives? Going further, do Banks, World Bank and maybe even the IMF invest in Derivatives? Thanks again!
@danndan6 one type of intelligence doesn’t always translate directly into another. what part don’t you get?
I’m Mensa and i still don’t f*cking get it
If Bailey doesn’t provide the turkeys, Terry can sue bailey for breach of contract. But if Bailey is insolvent, he won’t receive any damages.
if bailey doesnt provide the turkey will terry get the money back that he paid to terry…?? any ideaa…
@Linfone It seems like they are trading the future to make up for the past and ignoring today. They are also sacrificing the future.
@DrReaper Those are forward or future contracts, which are under derivatives.
@Linfone
They used to be called contracts but I think what is happening now is the government is paying companies to hold them in perpetuity. Also how come after all the bailouts QE2 almost none of the derivatives are gone. It’s like they never go bad. Lotto tickets go bad and so should derivatives. Someone is holding a lot of bad lotto tickets and they want taxpayers to pay for them. I say eat your losses even if they are 1.2 quadrillion.
@DrReaper Because they have 3 main uses: hedging, speculation, and arbitrage/price discovery.
Hedging is the largest use, followed by speculation and arbitrage. A lot of commodities (oil, wheat, etc.) need to be hedged so suppliers don’t lose a lot of money in case prices go up or down dramatically. Think about how many million or billion tons of commodities are consumed a year.
I couldn’t understand my college Finance professor but I understood this guy. He is simple and straight to the point.
So why are there so many derivitives? 1.2 Quadrillion seems like a lot to me.
It’s not all profiteering either; they use it a lot to diversify in order to reduce exposure.
This is exactly what happens on Wall Street, from a broker’s point of view. It is similar in that it happens after the IPO, after Goldman Sachs, Merrill Lynch, etc. sell their shares. Essentially, the butcher is Goldman Sachs, and the person are the brokers. Don’t get me wrong, Goldman Sachs and Merrill Lynch use derivatives as well.
