Mathematics is an essential tool for studying science and engineering, and calculus is one of the most important branches of mathematics for engineering. In this paper a new formula for evaluating ∫xneaxdx and a more generally applicable extension to polynomials are developed. This new approach illustrates the intimate relationship between differentiation and integration, and is simple enough for a freshman taking the first course in calculus to derive it. Although a closed-form expression for this integral exists, it is cumbersome and relatively more difficult to remember than the forms proposed in the paper. Also, the proposed formula readily generalizes to a larger class of polynomials, thus becoming much more useful. We show that these formulae are particularly important for the analysis and use of a broad class of signals commonly encountered in the classroom and in practical situations. The proposed formulae are applied to Fourier Series, Fourier Transforms, Laplace Transforms, and time domain convolution
