Who can solve this??

[math]f(x)=-1-\int_{0}^{x}\left ( 2*x-t \right )*f(t)*dt[/math]

blah blah take derivative second fundamental theorem of calculus blah

Fucking suckers, you got no idea. My son could solve that with his dick.
I'm not a robot.

>>7718063
how many integrals were you solving with your son's dick?

>>7718046
I assume that * denotes convolution?

I would assume * are products.

[math]f(x)=-1-\int_{0}^{x}\left ( 2x-t \right )f(t)dt[/math]

this is Indefinite integral
fucking waste time

Set x = 0 to get f(0) = -1.
Now differentiate:
f'(x) = x f(x) - 2 \int_0^x f(t) dt
Set x = 0 to get f'(0) = 0 and differentiate again:
f''(x) = x f'(x) - f(x)

A very simple ODE that can be solved with the usual methods.

Its not an indefinite integral... why did you say that?

>f'(x) = x f(x) - 2 \int_0^x f(t) dt
the fuck ?

i once saw jacob barnett give it a crack. he spent 3 weeks locked up in his office, bossing around undergrads and having them remove his waste in a bucket. the problem remains unsolved.
>>
>>7718153
my grandpa say that
>>
>>7718142
what the fuck is this ?
you need to write the step 1 by 1 m8

>>7718102
The fuck?

I tought I'd get any sign of inteligence in this thread...
