Objective c)

To overcome the difficulty of relating a component to the direction angle and the magnitude, the view is oriented in such a way that a right triangle can be clearly seen formed by the vector and one of the components, and also containing the angle related to such component. In the following figure it can be seen a view for the triangle formed when working with the component.

The view is updated for the other two components as well so that the students learn that regardless of the component, it is always going to be the cosine function the one that helps to relate the quantities, this is and .
