7.1: Definition of Laplace transform 17. Prove L {eat f(t)} = F(s – a) 18. Prove L {f'(t)} = sF(s) – f(0)
Definition 4.2.1. Let f : A → R, and let c be a limit point of the domain A.We say that limx→c f(x) = L provided that, for all ε > 0, there exists a δ > 0such that whenever 0 < |x − c| < δ (and x ∈ A) it follows that |f(x) − L| <ε .Use the definition 4.2.1 (ε and δ definition) on Understanding Analysis to prove limit when x goes to 2 (x2+4x+13)=15.

QUESTION 3 After use Laplace Transform to transform the following initial value problem X" +x=e-t, x(0) = 1,x'(0) = 1, S-2 you should get X(s)= (write fraction as (S-2)/(5-4)(8+6) for -). Then, find (s-4)(8+6) x(t)= L-?{X(s)}= (write 5/6 by 5 -30 6' e^{-3t} by e and sin(2t) or cos(3t) by sin(2t) or cos(3t)).
Use this definition of a right-hand limit to prove the following limit. EXAMPLE 3 x0 SOLUTION and L such that 1. Guessing a value for 6. Let & be a given positive number. Here a = so we want to find a number 0 x6 if then that is if 0 <x<6 then <E or, raising both sides of the inequality to the eleventh power, we get 0 <x if then x < This suggests we should choose 8= 2....
