Determine direction of a vector

WebIn summary, the direction of a vector can be determined in the same way that it is always determined - by finding the angle of rotation counter-clockwise from due east. Since the resultant is the hypotenuse of a right triangle, this can be accomplished by first finding an angle that the resultant makes with one of the nearby axes of the triangle. WebTo determine a direction in three dimensions, a vector with three components is needed. This vector is a unit vector, and the components of the unit vector are called directional cosines . Given a three-dimensional unit vector u u in standard form (i.e., the initial point is at the origin), this vector forms three different angles with the ...
