Excellent method sir. Hats off. Through this method I can solve any problem within a minute.

[rattitat]

so well explained! this 4 minute video put everything in place for me, thank you

[rajeshprajapati]

I also solved the last two examples using this method and got everything in place. You are amazing.

Valid means when proposition is tautology but it is not tautology how this problem will valid ??

[Andreatuzze]

this was the explanation I was searching for, you saved me thank u so much !!

[certifiedsmartass]

I have been using this method since you introduced rules of inference.

[arturvincent]

Very helpful indeed, I'm still confused of how to work with arguments that contain or connectors and not just and connectors

[adityaprasaddhal]

But still if it comes in exam, we have to solve using rules, can somebody explain me how to solve it using rules

[popoporiBN]

if the maths/computer tutorial video does not have a honking sound in the background, I do not trust it.

Your are so coool in these topics
Thank You

Show that the premises " It is not sunny this afternoon and it is colder than yesterday, " "We will go swimming only if it is sunny, " " If we do not go swimming, then we will take a canoe trip, " and "If we take a canoe trip, then we will be home by sunset" lead to the conclusion " We will be home by sunset."
Please sir apply your method in this problem.
Because I am not getting the same result using your method.

That was really helpful! Thank youu <3

A concern with you method I wanted to raise was, I think the argument should be written as T -> ( M v E ), not T -> M v E. Your conclusion is still true because M is still false but the reason is because M v E would mean f or f, which can not be true.

Check it is valid or invalid??
If the two sides of the triangle are equal then opposite angles are not equal .Therefore opposite angles are not equal

[skgaming]

Saw this question in 2005 math paper and was panicked and curious to know abt this

[rameezkhan]

How this is valid argument?? Then what happens when all the premises true and conclusion also true...thats also valid argument?

[dryusufkamal]

Sir, excellent illustration and explanation . Can you please name this method ? ( I need this to apply this method to test the validity of my assumption in one of my research case study).
Thanks and Regards,
Yusuf Kamal

[thankgodjosephakoh]

Sir pls d rul we need more examples on this short cute method

[FaiGal]

it's valid cuz it can be proven the argument conclusion is invalid/false?

[jessicabosworth]

Is there a way to turn on the closed captions with your videos?
