In arithmetic, changing from regular and tangential parts to Cartesian coordinates entails expressing a vector when it comes to its rectangular parts. The conventional element of a vector is the element perpendicular to a given floor or curve, whereas the tangential element is the element parallel to the floor or curve.
Changing between these two coordinate methods is important for varied purposes in physics, engineering, and geometry. For example, in fluid dynamics, it permits us to investigate the stream of fluids over curved surfaces, and in structural mechanics, it helps us decide the forces and stresses appearing on objects with advanced shapes.
