Answer:
The sum of the given vectors is
Step-by-step explanation:
For the given vectors (which are R³ vectors), the sum is simply the sum of each coordinate, if a general vector is written as
<u>the sum of two vector will be in each coordinate at a time</u>.
To illustrate geometrically the resulting vector in the space xyz
<em>we can say that the first coordinate is on the x-axis, the sencond on the y-axis, and the third one on the z-axis</em>, so the illustration will be a <em>vector starting from the center of coordinates, and ending in the coordinates 0 of the x-axis, 1 of the y-axis, and -1 of the z-axis</em>. <u>Or, in a plane yz (where x=0), a vector from the origin to the point 1 in y-axis, and -1 in z-axis</u>.
