You have a function f(x) = sin(x) and want to evaluate \( \int_{-\infty}^{\infty} f(x) \delta(x - \frac{}{2}) dx \). What is the result and why?
💡 Hint: Apply the sifting property directly.
Discuss how the sifting property would change if the function was represented by a step function instead, such as Heaviside's function. How would values be extracted?
💡 Hint: Consider the behavior of step functions when approached with delta functions.
