The resultant, or sum, vector would be the vector from the origin of the first vector to the arrowhead of the last vector; the magnitude and direction of this sum vector would then be measured.

Graphically, vectors are added head to tail to find the resultant vector. Mathematically, vectors are resolved into components using trigonometry and the Pythagorean theorem, useful for non-perpendicular vectors. Examples demonstrate that perpendicular vectors do not influence each other's components. The text also includes practice questions to enhance understanding of the concepts.
