Question

Dirac delta function.
Integral delta(t) from t1 to t2 for t1,t2<0

anonymous · Answer

I think it is 0 but am not sure

anonymous · Answer

Isn't it defined as the derivative of the Heaviside function?

anonymous · Answer

i think the dirac delta function is zero everywhere except at 0
so yes, the integral will be zero

anonymous · Answer

if i am not mistaken the integral $$\int _{-\infty}^{\infty}\delta=1$$

anonymous · Answer

some weird real tall function at $x=0$ and $0$ otherwise

anonymous · Answer

Thank you :)

anonymous · Answer

yw, but i would not take my word for it
maybe google

anonymous · Answer

I am sure now. I re read my notes and found it there too.
