Greeks (finance)
In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.
Use of the Greeks
The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.
The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Cameras
by: Wiz Khalifa[Verse 1:]
Oh, it's hardly a secret
You ain't gon stop tryna get where you going until you reach it
Always had them bars back in the day
When the same ones running up on you wasn't speaking
Look at all your achievements
You work hard so it'd be kinda hard not to believe that
You party every weekend (weekend)
Fuck em all who act like they ain't see it then
All them nights on the plane
Losses a nigga took, had to charge it to the game
Always wanted stardom and the fame
Learn to out smart em
And now it ain't no stopping the champagne from poppin'
The draws from droppin'
Us seeing muscle cars and coppin' em
Started off just a little less popular
[Chorus:]
Now you got a new place
You drive a new car
You smile for the cameras, live life like a superstar
Don't care what they say
You reach for the stars
Got everything you always dreamed or thought about
And everyone knows who you are
[Verse 2:]
Never gets boring
And haters in your face, you just ignore em
Don't know what they talking shit for
See niggas get theirs, you just tryna get yours
Therefore, you left all the people you care for
Hopped on a plane and got airborne
Seen all the bullshit and fell for it
But it's all good now
Cause the same ones that talk shit telling everyone you made it
Then you start seein' hoes you dated
And thoughts start getting jaded
Now your life's sort of different ain't it
Feel your scars knowin what your pain is
But what's it all worth if it's painless?
Say you wanna be famous
[Chorus:]
Now you got a new place
You drive a new car
You smile for the cameras live life like a superstar
Don't care what they say
You reach for the stars
Got everything you always dreamed or thought about
And everyone knows who you
are, are, are, are, are, are, are, are,
are, are, are, are, are, are, are,
who you
are are, are, are, are, are, are, are,
are, are, are, are, are, are, are
who you are
[Verse 3:]
Always knew I was this good
But never knew I'd be this good
Them niggas just starting, I've been doing it
Hear em talk but they ain't living my life
In the dark tryna get in my light
But chances I don't get em, dodge twice
Spendin' grands for hoes, this is the high life
And for the camera's posing this the high life
Bottles raising for my niggas not here
I pour out a couple sips
Blew em on the beach, I smoke for you on my trips
Them days I was younger I knew this life was the shit
But never like this
It's so amazing, we ain't gotta duck shots
We just pour and chase em
Ain't worry bout it, cause they gon hate
Know where I'm going, look where I came from
[Chorus:]
Now you got a new place
You drive a new car
You smile for the cameras live life like a superstar
Don't care what they say
You reach for the stars
Got everything you always dreamed or thought about
And everyone knows who you
are, are, are, are, are, are, are, are,
are, are, are, are, are, are, are,
who you
are are, are, are, are, are, are, are,
are, are, are, are, are, are, are
