          |  |  The inversion of Laplace transforms is performed using two methods: (1) the Zakian method and (2) the Fourier series approximation. Results are in agreement with analytical solutions obtained using the built-in function of Mathematica: InverseLaplaceTransform. The Zakian method presents problems for transcendental functions. The Fourier series gives better results when dealing with oscillating functions.
