Which matrix is a vector (points 1)

A unit vector is a vector whose length is one. Here is one way to picture these axes. Stand near the corner of a room and look down at the point where the walls meet the floor. The negative part of each axis is on the opposite side of the origin, where the axes intersect. Three-dimensional Cartesian coordinate axes. A representation of the three axes of the three-dimensional Cartesian coordinate system.

The origin is the intersection of all the axes. The branch of each axis on the opposite side of the origin the unlabeled side is the negative part. You can drag the figure with the mouse to rotate it. If you do that, you will be living in a mathematical universe in which some formulas will differ by a minus sign from the formula in the universe we are using here.

Your universe will be just as valid as ours, but there will be lots of confusion. We suggest you live in our universe while studying from these pages. Sums, differences, and scalar multiples of three-dimensional vectors are all performed on each component. A vector in three-dimensional space. You can drag the head of the green arrow with your mouse to change the vector. GeoGebra Topic Question English. Category English. Tags v4. How to attach a column vector to a column and row matrix.
