Types of Matrices and Matrix Addition

[@girmalegese5754]

your explanation is very clear for every body ,thank you so much

[@quahntasy]

Thank you so much. This really helped in revision.

[@SeriousStudent603]

for sq. matrices 1:52 vector (vertical) 2:15 3:11 to add / subtract matrices, they must hv same dimensions (same no. of rows & columns). 5:40 add is commutative but sub is NOT .

[@theonlinezone6904]

thanks for all the videos, the quality is awesome

[@nayanika9277]

This really helps! Thank you very much!

u can also add another column & row of zeroes in 2x2 matrix to make it 3x3 & then add it to 3x3

[@atheron]

Hey Prof.Dave nice videos 👍

[@FeedYourBrainChannel]

The matrix appears to be pretty complicated

[@Salamanca-joro]

What??! Bro its like asking 1+1 ? how it is complicated

[@aydnsafi2054]

@@Salamanca-joro i was stuck at gauss method for 3 days! maybe i'm dumb

[@veerrajuannamdevula9939]

As i knew angle is the openess between the two rays then don't that change if we move far from the vertex??

[@Syntaxxed]

Linear algebra teacher asked us to forget everything we learned in highschool about vectors lol

[@veerrajuannamdevula9939]

Sir(literally a childish question but plz don't care)don't the angle change if we move away from vertex as the space between the rays increases?

[@ProfessorDaveExplains]

i'm not sure i understand the question, you mean does the angle change if you move the location? no that wouldn't change the angle.

[@veerrajuannamdevula9939]

Sir what's the difference between a vector and a matrix?Are all matrices vectors? (Literally waiting for your videos on vector space my mind messed up with all the stuff on vectors due to lack of clarity)so plzz help me as a fellow being

[@ProfessorDaveExplains]

no no, totally different constructs! don't worry i'm shooting all the linear algebra stuff next week it's coming soon

[@robot-ec9rh]

Thank you so much.may god bless you.i don't understand my teachers.🤔🤔!!.you are like a god for me😄😄. please make videos on abstract algebra too(please! please! please!please!)

[@letsspilltea9334]

god is jesus

[@rajeshannamdevula1893]

Before getting into limits is it necessary to know about functions? If yes why?

[@ProfessorDaveExplains]

well yeah you should definitely know about functions before getting into calculus, that should be covered in algebra. check out my algebra tutorials, i have lots!

[@Rakesh-wj9vn]

Plz make rest videos about this chapter

[@ProfessorDaveExplains]

patience! you will get everything you want over time.

[@mathworld3962]

good teacher

[@trieuhuyvan5020]

‎Thank you so much

Why cannot the curve be differentiable at sharp points sir?

[@ProfessorDaveExplains]

it's not a continuous curve!

[@carultch]

Because there is an abrupt change in what the derivative is, on both sides of the sharp point. So kinks and cusps are not differentiable, because you get conflicting answers for what the derivative is, depending on which side you approach the sharp point. The discontinuity in the derivative means it is not differentiable.
