QUICK!!
WRITE A FUNCTION THAT FINDS THE DERIVATIVE AT A POINT OF A FUNCTION!!
OR THIS BRIB WILL STAB YOU!!

Fuck off OP.
Symbolic or numerical differentiation?
I don't know what you want me to do.
def deriv(f, pt):
h = .00001
def ret(x):
dfxdx = (f(x+h)-f(x))/h
return "{0:.4f}".format(dfxdx)
return ret(pt)
What's a "BRIB"?
u mad faget
an intentional misspelling of birb
numerical
derivative((x*x), 10) will equal 20 because the derivative of x*x is 2x, and 2(10) = 20
deriv f pt = ((f (pt + 0.00001))-(f pt))/0.00001
bümp
/* probable FUCK UP on the function pointer syntax, but who the hell cares? */
double derivative(double (*func)(double), double point)
{
return
(func(point + EPSILON) - func(point))
/ EPSILON;
}
Here's you're (you)
BUMP
op plz provide feedback
Legitimately unexpected.
Woah
hopefully the bird will kill me
nigger
>h = .00001
HAHA good one user.
Lys
top kek
>only one who used epsilon instead of something like 0.00001
Well done
D(f(x))
this made me laugh
deriv f x = (f (x + 1e-5) - f x) * 1e5

Top zozzle even Sup Forums is retarded.
heh

Worse than OP
Why's the right side of this image blurry?
You
>in 2017
FUCK
And YOU tell OP to fuck off? How bout you fuck off buddy.
>How bout you fuck off buddy.

Kek return to reddit newfag
function [y] = diffatpoint(f,x)
y = feval(matlabFunction(diff(f)),x);
end
>Not coding in the best programming language.
I bet you fags don't even have time to get a coffee while I your program runs.
Y
Why do you have a function inside a function?
>Current year
>Not saying maximum milkdude
I didn't expect it, because of that here is your (you)
>X*X is 2X
No
Read it again, fuckbib, the derivative of x*x is 2x
Started reading, 3 lines in got bored and decided to skip to the last line, worth it lads
You sneaky faggot
I don't have a CS degree. I majored in business studies. Guess I am dead then.
The original bird poster at least had the decency to post his own reference solution, you pathetic copy cat.
What's the derivative? Why do I need that?
>What's the derivative? Why do I need that?
It is one of the most important concepts in mathematics and one of the central topics of analysis.
In simple terms it is the slope of a function at a given point.
It is used in nearly every field from economics to engineering.
