## engr1988 Group Title Dirac delta function. Integral delta(t) from t1 to t2 for t1,t2<0 one year ago one year ago

1. engr1988 Group Title

I think it is 0 but am not sure

2. wio Group Title

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

3. satellite73 Group Title

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

4. satellite73 Group Title

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

5. satellite73 Group Title

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

6. engr1988 Group Title

Thank you :)

7. satellite73 Group Title

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

8. engr1988 Group Title
