Reflexive, Symmetric and Transitive Examples

[Blogdorf]

What you're doing is not clear at all. I have no idea what your rules are for drawing arrows and can't follow the arguments. Will look somewhere else for instruction.

[AaronTesf]

should've started with definitions first to clarify for your viewers

Thanks for the video!

You say that 1.)  is transitive because you can't prove it's not. Does that also count for symmetry and reflexivity?

[Kimandr]

If we express the question number 1 in different expression.
would it be {(1, 1), (2, 2), (3, 3)}

Thank you so much! I couldn't understand it in class. This was a very good example to learn from

[privatesnafu]

Really appreciate this video. Really helped me understand what transitive was!

[tomas]

in the second example isn't the relation transitive because we have {( 1, 1), (2, 2), (3, 3), (1, 2), (2, 1), (2, 3), (3, 2)}. so we have (1-->2) and (2-->1) and we get (1, 1) and its there in the relation, so we proved that it's transitive. or we should prove it for all the elements.

in figure 2 isn't it true that the function mapping these two sets together is not a function since you can have more then one output for the same input?

[janhavideo]

If we are given a zero-one matrix how do we determine if it is transitive?

[valentinkadushkin]

In your first example, there is no arrow from 1to3 either?! It's only 1, 1 2, 2 3, 3

[banglalovesong]

Can I use one edge more than one time to make transitive.??
pls ans me pls pls pls
