Homework Equations
The Attempt at a Solution
I know that the dirac delta function is zero everywhere except at 0 it is equal to infinity:
[itex]\delta(0)=\infty[/itex]
I have to express the integral in terms of function f only and i am unsure how to do this.
Do I have to use integration by parts?
Thank you very much in advance
