    Vector
In summary, a collinear vector is a vector that lies along the same line as another vector. In the given context, AB and DE, as well as AB and ED, are collinear. The magnitude of a vector is its length, and in this case, AB and BA have a magnitude of 5 cm. The magnitude of BD is equal to the magnitude of AE, and also the magnitude of AC is the same as BF. When searching for a collinear vector to AD, it must be in the same direction, such as EB. However, if EB is collinear, so would BE. The lines BC and FE are parallel to AD. The remaining exercise, Q b), is still unresolved.

Homework Statement
I've begun this question. I'm not sure what a collinear vector is or how to show the exact magnitude. Also, if someone can confirm the top two, that'd be great!

A vector that lies along the same line. The idea is that a vector starts in the origin and points in a particular direction. In that context, AB and DE are collinear and so are AB and ED
Also, if someone can confirm the top two, that'd be great!
I can't. But I can confirm the top one :wink:

Magnitude is length. So AB and BA have magnitude 5 cm.

So then the magnitude of BD is AE.
What could possible be the collinear vector to AD??

No. AE is a vector, not a magnitude (i.e. not a number, a scalar)
But the statement "The magnitude of BD is the same as the magnitude of AE" is correct. Idem AC and BF

So you search for one or more lines parallel to AD

So then collinear to AD would either be BE or EB

BE points in a different direction than AD

It has to be in the same direction. I will use EB
 
  • #8
Clearly, EB also points in a different direction than AB
If EB would be collinear, so would BE !

Don't you see any lines at all that are parallel to AD in the figure ?

Correct. So, where are we now with this exercise ?

I think Q b) remains
 

What is vector labelling?

Vector labelling is the process of assigning labels or names to features on a map using vector data. This allows for a more precise and organized representation of the data, making it easier to interpret and analyze.

What are vector mapping services?

Vector mapping services involve the creation, manipulation, and analysis of vector data to produce accurate and detailed maps. This includes tasks such as digitizing, editing, and labeling vector features to create a visual representation of the data.

What are the benefits of using vector labelling and mapping?

Vector labelling and mapping offer numerous benefits, including improved accuracy, scalability, and flexibility. Vector data is also more compact and efficient compared to raster data, making it easier to store, share, and analyze.

What types of data can be used for vector labelling and mapping?

Vector labelling and mapping can be done using a variety of data sources, such as satellite imagery, aerial photography, GPS data, and survey data. The type of data used will depend on the specific project and its requirements.

What industries use vector labelling and mapping services?

Vector labelling and mapping services are used in a wide range of industries, including urban planning, environmental management, transportation, agriculture, and natural resource management. These services are also commonly used in GIS (Geographic Information Systems) applications.
