摘要：
The goal of this work is show how the comparative study of several techniques to solve diferential equations can be a important teaching tool in the learning of a mechanical resonance phenomenon. The forced damped harmonic and parametric oscillator are studied by method of variation of parameters and Green's method. The importance of a priori suppositions is also discussed.
