Abstract: The anisotropies in the CMB conform nowadays the most precious dataset in cosmology and because of that its detection in 1992 supposed a crucial event. The analysis of this data provides evidences of dark matter and the in ation process. It also exists a relation between these anisotropies and the density perturbations, which evolved making the universe structures. In this work, we will explain what density uctuations are, how they evolved and how can they be mathematically represented to understand the shape of the anisotropies spectrum. We also explain how this spectrum can be used to give the cosmological parameters of a model and how the anisotropies can be represented to make a mathematical analysis
