Expression "There's no point of/in"

[Pedro]

Hello, how is it going?

Take a look at this examples:

1.- There´s no point IN/OF sending you to school
2.- What´s the use OF/IN sending you to school?
3.- There´s no use OF/IN sending you to school
4.- It´s no use sending you to school

I have realized that the prepositions in/of are used indistinctly when using the sentences "there´s no point..."
"there´s no use...", "what´s the use...". Is that correct? Or is there any difference between the usage of "IN" and "OF"?

Thanks in advance!

Hello,

There is no point in...
What's the point of...

Hope it helps

[Pedro]

Thanks indeed!

And, what about "use of/in"? Is it the same as "point of/in"?

1.- What´s the use OF sending you to school?
2.- I don´t know what is the use OF sending you to school
3.- There´s no use IN sending you to school.

Are these three examples right?

Thanks again!

There is no use (in) arguing any more.
It is no use trying to escape - no one ever gets out of here.
Try not to get depressed - after all, what's the use of worrying?
What's the use of...? (ALSO What use is...?)

Hope it helps!
