Resumen
The study of levels of vibration and noise of electrical induction motors leads to mathematical models in which appears an ordinary diffrential equation of first order with trigonometric coefficients. It can be replaced by an infinite system of differential equations with constant coefficients . A method which produces an analytic expression approximating the exact solution is described. This expression is a sum and its components are determined by the solution of a system of linear algebraic equations, which is solved with the help CJf a computer algebra system.
