Why a unit vector is aone type of vector but a vector is not a unit vector?
A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
What are unit vectors?
a unit vector is a vector which has exact same direction and has its length or magnitude equal to one
What is the difference between unit vectors and column vectors?
a unit vector is any vector with length or absolute value 1. A column vector is any vector written in a column of since we say an mxn matrix is m rows and n columns, a column vector is mx1 matrix.
Can you add three unit vectors to get a unit vector does your answer change if two unit vectors are along the coordinate axes?
Yes., and their being along the coordinate axes does not change the answer.Consider the vectors: i, -i and j where i is the unit vector along the x axis and j along the y axis. The resultant of the three is j.
If the sum of the two unit vectors is also a unit vector find the magnitude of their difference?
resultant

Dot product of unit vectors of cartesian and cylindrical coordinate system?
Unit vectors are perpendicular. Their dot product is zero. That means that no unit vector has any component that is parallel to another unit vector.

What is the importance of unit vector?
By using unit vectors we can cure the cervical cancer and we can dispersal the seeds

Cross product is not difine in two space why?
When performing the cross product of two vectors (vector A and vector B), one of the properites of the resultant vector C is that it is perpendicular to both vectors A & B. In two dimensional space, this is not possible, because the resultant vector will be perpendicular to the plane that A & B reside in. Using the (i,j,k) unit vector notation, you could add a 0*k to each vector when doing the cross product, and the resultant vector will have zeros for the i & jcomponents, and only have k components.Two vectors define a plane, and their cross product is always a vector along the normal to that plane, so the three vectors cannot lie in a 2D space which is a plane.
When do we use vector algebra in daily life?
In real life unit vectors are used for directions, e.g east, north and up. The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors.
What is the maximum resultant possible when adding a 13-unit vector to an 18-unit vector?
31
If A and B are two unit vectors and is the angle between them Then A B is a unit vector Find?
Your question is kind of confusing, but if you're asking what the angle between two unit vectors A and B is, then the answer is: the inverse cosine of the dot products of A and B.
What are unit vectors used for in real life?
In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level.
