This applets allows students and teachers to investigate the components of a vector. [br]Two sliders input the magnitude of the vector, and its direction measured in degrees counter-clockwise from the positive x-axis.[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 scalar-components of the vector are shown along with their calculation.
