What does this notation mean?

What does this notation mean? : [a, b) , [a, b]

 

[Harry_the_cat]

[a,b) means x such that \(\displaystyle a\leq x<b\)

[a,b] means x such that \(\displaystyle a\leq x\leq b\)

 

[Vikash]

[a,b) means x such that \(\displaystyle a\leq x<b\)

[a,b] means x such that \(\displaystyle a\leq x\leq b\)

Dude like there is no meaning for both interval notations combined right?

 

[Harry_the_cat]

Dude, they are two separate statements.

Got it bro ...because in the edexcel spec they have given like this...maybe its a misprint...

 

[Harry_the_cat]

Yeah bro, seems to be a misprint.
Basically the round bracket ( or ) means that value is NOT included. And the square brackets [ or ] means that value IS included.
