http://web.eng.ucsd.edu/~massimo/ECE45/Homeworks_files/ECE45%20HW4%20Solutions.pdf WebYou may have noticed a difference between this definition of a scalar line integral and a single-variable integral. In this definition, the arc lengths Δ s 1, Δ s 2,…, Δ s n Δ s 1, Δ s 2,…, Δ s n aren’t necessarily the same; in the definition of a single-variable integral, the curve in the x-axis is partitioned into pieces of equal length.This difference does not have …

Webthat for any f(t) the function f(t) u(t − a) −u(t −b) equals f(t), when t ∈ (a,b), and 0 otherwise. Now consider again f(t) = (−1, t ≤ 4, 1, t > 4. This, using the previous, can be represented as f(t) = −1 u(t) −u(t−4) +1· u(t−4) = −u(t) +2u(t−4). Now, using Property 6 , L {f} = L {−u(t)+2u(t −4)} = − 1 s +2 e− ...

WebFirst of all, we can easily say that for any value other than t = 0, t δ ( t) = 0 since δ ( t) = 0 and t is finite. However, for t = 0 things are more interesting. δ ( t) is infinite while t = 0. I'm sure this could be treated as some sort of limit of a function that approaches the dirac delta function. However, my question arose in a ...
