sir apne input glt likhi hai 3 input k liye 4 true hotae hai 4 false and and also we can solve it by the concept of binary no . the bigest 3 digit binary no. is 8 out of which 4 true and 4 false so in p there are first 4 true else 4 false , in q 2 true and 2 false repeat it once , and in r one true one false repeat this 4 times
Sir ke khudke concept clear nhi h . Phle khud prepare hokr aao tab padhao , kuch bacche exam se ek din phle video dekhne aate h aur unhe lgta h aap shi padha rhe ho , aap isko as a advice lo ya bezzati lo , dobo hi badhiya hoga kyunki sir hum bacche aap pr wishwas krte h ki aap shi padha rhe h , agr galat h to atleast comment box me daal do ki kahan kya kya mistake hui
So i request you to upload lectures on these topics 1.propositional equivalences 2.predicates and quantifiers 3.nested quantifiers 4.rules of inference 5.proof 6.introduction to proofs 7.set operations 8.functions 9.sequences and summation 10.relation and their properties
Those who are saying they are getting toutology your answer is right but the ←→ the arrow in video is not a arrow for bi-conditional its show equivalent....check your answer it should be equivalent to p now
Bro you have to understand first, the question is saying Pv(PvQ)p and p, question is trying to say show the equivalence relationship in P and Pv(PvQ)P. You have to get the truth table of (Pv(P^Q)P and match it with the truth table of P.
I think there is a flaw in the last question. Because the original bi-implication proposition is generating tautology, otherwise I couldn't figure out any kind of equivalency in this question. Correct me if I am wrong.
Equivalent hain sir but aapne biconditional symbol daal diyaa beech me naa k equal kaa ton maine usse calculate kr liyaa ton tautology aa gyi mtlb agr tautology aaye ton vo equivalent hain ok got it! & hn suniyee suniyee tnku so much ❤😂

Respected sir, I want to inform you that in the question no. 4 solved in this video at timestamp 18:50 Mins. in the column of the q in the table you mentioned the T and F values of R and in R you have mentioned values of Q so accordingly your ans is incorrect, as in Q value must me TTFFTTFF and you have entered TFTFTFTF and vice versa for R column.
Hello sir, I'm Purav from Surat, Gujarat. I want to inform you about Q3. Based on tautology. the truth table is incorrect and I have checked the solution twice, kindly request you to have a look on the particular question no. 3 based on tautology. and thank you for making subject more easy.
For those :- kisko kiske equivalent krna -> and ke left side ko and ke right side (P) se equivalent krna hai -> if am wrong then tell me -> and thank you so much for such videos
Sir's teaching method is so knowelegeble, but my one question why sir is saying students and i am listening it ae sun... 😂 ,Is it me only or anyone else too ?
For question you gave at the end of the video, they are not equivalent the expression on the left is a tauntology while P is not. Please correct me if I am wrong.
Can anyone please answer this question for me? I'm really confused! Q. For an implication "p implies q", if "q" becomes hypothesis and "p" becomes conclusion, then it is ____ of the given implication "p implies q".
2 true and 2 false for " p" and 4 true in p v (p^q)p thats why it is not equivalent BICONDITIONAL" P"nehin hota toh hota but last wala tautology ho sakta hai
for checking tautology, sometime we check only last column wheather all are true or not, in some place i seen new logic that Sir are checking if last one is true and all corresponding are true, then its a tautology . justify why and where to use which one?
Inverse : we simply put not But in contrapositive, first we do converse and put not on it Hope this helps you This is superficial information for clearing your doubt .
