This applets allows students and teachers to investigate the components of a vector. [br]Two sliders input the x-, and y- scalar components[br]A check box toggles the visibility of the rectangle whose diagonal is the vector in question.[br]Two toggle buttons are provided:[br]One toggles the angle shown[br][list][br] [*]Between vector and positive x-axis[br] [*]Between vector and positive y-axis[br] [*]Between vector and x-component vector[br] [*]Between vector and y-component vector[br] [*]No angle[br][/list][br]The other button toggles through different pairs of component-vectors.[br]At the lower left the magnitude of the vector as well as the angle between it and the x-, and y-axes are shown.
