Vector components allow us to break a single vector quantity into two (or more) scalar quantities with which we have more mathematical experience. The number of (1-form) hyperplanes intersected by a vector equals the inner product. After finding the components for the vectors A and B, these components may be just simply added to find the components of the resultant vector R. The components fully specify the resultant of the vector addition, but it is often desirable to put the resultant in polar form. Consider how one would find the components for vector A if the 'y' axis were rotated as shown in the figure (the 'y' axis is rotated to form the new axis 'y', where as the new 'x' axis is not changed and simply overlays the old 'x' axis.) If it points to the right, it is positive. 3. If we know the coordinates b(xb, yb) Vector v in Figure 1 has an initial point at the origin (0,0) and is said to be in standard position. Rectangular form, on the other hand, is where a complex number is denoted by its respective horizontal and vertical components. vector for the northwest corner of Liberty Park in both magnitude and direction form and unit vector form.
