The present article is meant as a bridge between theory and practice concerning Girsanov theorem. In the first part we give theoretical results leading to a straightforward three step process allowing to express an asset's dynamics in a new probability measure. In the following sections we apply this three step process. The first application consists in expressing a foreign asset's dynamics in domestic currency which leads to the well known quanto adjustment formula. The second application is the expression of the forwards' dynamics under Libor Market Model using a unique probability measure. The final application consists in expressing foreign short rate Hull & White dynamics under domestic measure.
