when the x>0,then the theta is equal to 1
So the theta =0 when x=0
in the second term of the integral,
it starts to integrate the function from "0 "to infinity(see the yellow loop inside)Since the" 0 "should not be included ,otherwise theta(0)=0 and (0*df/dt)=0
but why the 0 is still included in the integral to integrate the integrand!??
Sorry
i got confused
can anyone help me
thank you!??
