Chapter 8: Q4P (page 458)

Show that $\int_{- \infty}^{\infty} f_{n} (t) d t = 1$ for the functions $f_{n} (t)$ in Figures 11.3 and 11.4.

Short Answer

Expert verified

The given function is verified

Step by step solution

Given information

The given expressions are $\int f_{x} (t) d t = 1$ .

Definition of Laplace Transformation

A transformation of a function f(x) into the function g(t) that is useful especially in reducing the solution of an ordinary linear differential equation with constant coefficients to the solution of a polynomial equation.

The inverse Laplace transform of a function F(s) is the piecewise-continuous and exponentially-restricted real function f(t)

Verify the given function

Show that

$\int f_{n} (t) d t = 1$

Where

$f_{n} (t) = n e^{- n (i - r_{o})} t > I_{0}$

$f_{n} (f) = 0$

Otherwise

$\int_{f_{n}} (t) d t = \int_{i} n e^{- n (t - n_{0})} d t$

Solve further

$\int_{0} f_{n} (t) d t = n e^{n h_{n}} (\frac{e^{- π}}{- π}) \int f_{n} (t) d t = e^{n + 0 - n + 0} \int f_{n} (t) d t = 1$

Thus, verified.
