Laplace Operator laplace Laplace transform. L = laplace(F) is the Laplace transform of the sym F with default independent variable t. The default return is a function of s. If F = F(s), then laplace returns a function of z: L = L(z). By definition, L(s) = int(F(t)*exp(-s*t),t,0,inf). L = laplace(F,z) makes La function of z instead of the default s: laplace(F,z) <=> L(z) = int(F(t)*exp(-z*t),t,0,inf). Example: syms t f(t) f(t) = exp(2*t)*sin(4*t) F = laplace(f) Exercises: Find the laplace transform of the following functions: 1. fi(t) = 1 2. f(t) = (3e2¹ +6sin51 +21²)2 3. f3(t) = (2sin(2t) + 3cos(51))3 sin(31) 4. f4(t) = t 3 % Defining the variables and function to be used % Expressing your function and identify it as a function with t as independent variable. x≤2 5. fs(t)=5 2≤x≤r R≤X 0

Laplace Operator
laplace Laplace transform.
L = laplace(F) is the Laplace transform of the sym F with default independent variable t. The default return is a function of s.
If F = F(s), then laplace returns a function of z: L = L(z). By definition, L(s) = int(F(t)*exp(-s*t),t,0,inf).
L = laplace(F,z) makes L a function of z instead of the default s:
laplace(F,z) <=> L(z) = int(F(t)*exp(-z*t),t,0,inf).
Example:
syms t f(t)
f(t) = exp(2*t)*sin(4*t)
F = laplace(f)
% Defining the variables and function to be used
% Expressing your function and identify it as a function with t as independent variable.
Exercises:
Find the laplace transform of the following functions:
1. fi(t) = 1
2. f₂(t) = (3e2¹ +6sin5t +21²)²
