In the first 3 minutes I understood everything better than after 4 hours of lectures and hours of watching other KZbin videos. Thank you so much!!!

These are some of the best math videos on YT. Other math YT-ers should take note. Aside from good content: 1. high resolution, 2. good mic/clear audio, 3. clear annotations. Not sure why others can't just buy a good microphone and put it by their mouth rather than putting it across the room, in their waving hand, in the kitchen sink, not plugging it in, handing it to their crying baby....

[@WrathofMath]

Thanks so much! Though it took me nearly 6 years to be making the videos this high quality, it's all a learning process!

[@justinpalmer9387]

God send, my prof did the composition of groups without explaining what he was doing at all and I was so lost, video helped alot :)

[@isthisbadbnumber]

thank you so much you’re a student life saviour 😭

[@namelessflower7]

Thank you! You made everything so easy to understand.

[@misterentername8869]

These are amazing explanations, clear and mentions everything! Thank you, this deserves more views.

[@WrathofMath]

Thank you, that's precisely what I've been trying to achieve with the Abstract Algebra videos. Lots more to come in the playlist: kzbin.info/aero/PLztBpqftvzxVvdVmBMSM4PVeOsE5w1NnN

[@turefu8681]

Thanks a lot for this explanation. It helps me with a problem troubling for two days.

[@WrathofMath]

Glad to help! Check out my playlist if you're looking for more abstract algebra! kzbin.info/aero/PLztBpqftvzxVvdVmBMSM4PVeOsE5w1NnN

thank you a lot for this explanation, now this topic is much clear for me!

[@shwetabhsingh5437]

Lovely video, great conceptual clarity, this seems to be missing from a lot of physics lectures which involve group theory. Thanks.

[@WrathofMath]

You're very welcome!

[@homqua9613]

Thanks so much, your explanation is clear 💛

[@WrathofMath]

Glad to help, thanks for watching!

alpha is its own inverse because it is a transposition. i.e., any 2 cycle is its own inverse. The cycle decomposition of alpha is (1 2)(3) = (1 2). Hence, (1 2) is its own inverse as is any other transposition. Hope this helps anyone else studying for their abstract algebra final!

[@estherlevenson1835]

Thank you so much. I'd like to know more about the relationship between symmetry groups and permutation groups.

[@FMTanmayChopra]

Wonderful man, really clear explanations.

[@WrathofMath]

Thank you!

[@ParvejBiswas-qi4re]

Such a great math❤ explanation ❤

[@ismailadekunle1978]

Thanks so much for his video❤

[@WrathofMath]

Thanks for watching!

[@Bertilsdotter1]

Very good explained... Big thanks

[@WrathofMath]

Glad to help - thanks for watching!

You're welcome!

[@backiyalakshmi5990]

Thank you so much sir

[@WrathofMath]

Most welcome!

[@tirtahadith]

Done (but i think i need to rewatch it again multiple times

[@DrMATHJO]

Thanks for this,🙏🙏

[@prianborah]

Hi, this is a fantastic video. Could you make a video on A4 discrete symmetry group and its character table and what its irreducible representations like 1,1',1'', and 3 means, and also its multiplication table??

[@jaydevdeshmukh3831]

In your table at the end of the video, Why does Beta and Beta lead to delta? Should it also not have identity there? Same goes with Delta and Delta which is giving Beta.

[@mzarinchang3744]

Thats so cool....I thought that if a=a^(-1) then a must be the identity.......but this example showed that its not neccessarily true.....

[@xibbit6322]

my teachers making us do fuunction composition from left to right because he prefers it but no one uses that... its so annoying and confusing :(

[@ma.lourdezs]

Hi! Can you explain the general associative law?

[@ismailadekunle1978]

Can you do a full tutorial on Groups 😢❤

[@WrathofMath]

Like this you mean? kzbin.info/www/bejne/mpemf32jiZVgq6s&pp=ygUUd3JhdGggb2YgbWF0aCBncm91cHM%3D

@@WrathofMath thanks so much

[@danielrosen4496]

Wondering if Set is infinite,

[@WrathofMath]

Which set? I'm not sure what your question is. If you're asking if there are infinite permutation groups, the answer is yes. For example, one permutation on the reals might swap the positives and negatives and keep 0 fixed.

[@MYTHBuSS]

Please Solve This Problem!! My Maths Teacher Asked me to Prove that For Area of Square =, 1/2 x d x d Please help 😌🔥
