This is the best video one can find online to understand first order logic. Just watched the whole thing at 2x speed and everything is crystal clear. Take a bow sir! You are amazing!
At 34:37 for the RHS side (conclusion side) you have treated both the x (two x for two 'there exists' symbols) as same {saying that anyone of Raju or Rani must pass physics or chemistry which is not necessary as Raju can fail physics and Rani can fail chemistry which will make RHS false } but for the immediate next question you have treated both the x as different . How is this possible? Thanks
hey man in 37:46 wen raju passed in both physics and chemistry and say some fellow also passed in both phyysics and chem then how can u say in the r.h.s that it is false??
Home work is given by u at 38:00 A->B is false and what would be B->A , i'm getting it true becoz, if lhs is true then rhs will automatically true, in lhs allready condition is with both p(x) & Q(x). So lhs will true
sir at 19: 15 it is possible that every student might have passed physics but not chemistry or vice versa then..how can we get false for both case in rhs..plz clear my doubt sir..
in your case also, in RHS one of the terms must be false which will make RHS overall false. Remember your target is to create a True false case and there are many cases there. You have to only focus to get true false case. Hope this clears.
Nice explanation

This playlist is GOLD! Thank You Sir! ♥
Maja Aaa gaya Thank you so much😊
amazing explanation sir, really helpful before gate exam thank you
Thank you so much, well explained and excellent video!
best discrete maths lectures ever seen. thank u so much sir.
Well explained with nice examples. It was easy to understand.Thank u Sir for clearing my all doubts related to FOL.
Brilliant idea! Wow! Thank you Sir
Excellent faculty for discrete maths.....
What is the digital equivalence to [for all x for some y P(x,y)??
there is no digital representation of above logic that you have written.
if any, then answer.
At 34:37 for the RHS side (conclusion side) you have treated both the x (two x for two 'there exists' symbols) as same {saying that anyone of Raju or Rani must pass physics or chemistry which is not necessary as Raju can fail physics and Rani can fail chemistry which will make RHS false } but for the immediate next question you have treated both the x as different .

yes sam qstn..
great sir and thank you so much

Nice video but at some point you make us too confused about your concepts..
great explanation !!
explanations are easy to understand
Thank you sir.
thanku kiran ....
Crystal clear... 😊
At 37:00 u proved that A>B is not valid and at 39:00 u proved it right
well explained sir
Home work is given by u at 38:00 A->B is false and what would be B->A , i'm getting it true becoz, if lhs is true then rhs will automatically true, in lhs allready condition is with both p(x) & Q(x). So lhs will true
for all x [p(x) or q(x)] thereexists x p(x) and thereexists q(x) it is equal am i right sir plaease tell me
Nope
the timestamp of 29:48 has seperate fanbase.. Very good video sir. You should start making professional videos like Knowledge Gate
