Here we define what a regular language is, in that it corresponds to a DFA (deterministic finite automaton). All that is needed is for the DFA to exist, and not necessarily to give the DFA precisely. We also give some examples of regular languages that we have seen before.
1. Every finite set represents a regular language.
2. Given an expression of non-regular language, but the value of parameter is bounded by some constant, then the language is regular (means it has kind of finite comparison).
3. The pattern of strings form an A.P.(Arithmetic Progression) is regular(i.e it’s power is in form of linear expression).

Please make a video on Pumping Lemma for regular expression

[ramch]

Excellent sir..no one explained clearly like you

[softtecheducation]

Really very nice sir u have a bright future 👍👍👍👍. On teaching side, your explanation without any break r confusig r hesitating, very well keep it up

In WXW^R, if w contains a 3 length string then let, it can be start with a and end with a in W^R but what about the other char of the W are they reversed or not in W^R because this expression cannot able to tell about the a(a+b)*a + b(a+b)*b other

L=a^m b^n | m+n=even It is said to be regular.
There exists a functional dependency. If m=1(odd) then n= (odd) so the value of n depends on the m value, then why it is said to be regular.
❗❗ This is not in the video. I have a doubt on this question. To clarify this i came across the video ...could somebody explain me this.

Why this is not considered as Regular ?
a^n . b^n | n>=0

we can write its Regular grammar then why is it not considered ?
Regular grammar = S = a.S.b | epsilon

[ananthu]

13: sir why it is not regular..can you say it in english

[ahadkhan]

No offense but

He nailed TOC

[ANURAGHANDA-iypb]

Sir ismein answer mein star ki jagah plus aayega as x and y have to take something

[athiyanavneeth]

Sir, wcw^r strings regular expression
Generates strings not in L which violates the property that regular expression shldnot generate strings not in L
