Find the Laplace transform

F(s) = L{f(t)} of each of the following functions.

(i) f(t) = t^2 / 3 ( e^4t + e^−4t )

Hint – Use the Linearity Property and the Table of Laplace Transforms.

(ii) f(t) = e^3t ( sin(t) + cos(t))

Hint – Use the Linearity Property and the Table of Laplace Transforms.

(iii) f(t) = t( sin (2t) + cos (2t))

Hint – Use the Transform Derivative Principle and the Table of Laplace Transforms.
