INTERVALS #intervals
INTERVAL : Interval is the subset of the real line R. There are few kinds of intervals . i. (a,b) = {x/xꜪR,a<x<b} pronounced as open interval a,b This interval containes all the numbers between a and b except a and b. ii. [a,b] = {x/xꜪR,a≤x≤b} . . . . . . .closed interval a,b this interval contains all the numbers between a and b together with a and b. iii. (a,b] = {x/xꜪR, a<x≤b} . . . . . semi left open interval a,b or semi right closed interval a,b This interval contains all the numbers between a and b together with b only. iv. [a,b) = {x/...
