por favor coloquen los subtitulos en formato "Archivo de subtítulos" (incluye códigos de tiempo)
en lugar de "transcripción de audio", esto para que mejore la calidad y la precisión de las traducciones

but in the determinant of B you have to suppose that b-a and c-a are not equal to 0.

i like math in general, i dont know it seems so intuitive and fun, even thou it sounds weird. i studied most of my math courses online prop to this.

Maybe some maths rules doesn't make any sense on my mind, therefore I am not able to understand what's going on in the matrices. I got very annoying about my brain.

for the det B why did we use linearity in 1 step?,since linearity has to do with each row separately,right?

Why do not open Matrix (B) directly? or without any row/column operation

?? I never expected from MIT that they teach wrong.. In first question, you can't subtract 3rd row from 2nd row because 2nd is changing.. Never expected from mit.. Is this the knowledge MIT teacher have..??? Loosers. ??

I have never seen the notation with which matrix C is expressed (that kind of "product") could anyone explain please?

Excellent video. Please, help me with this linear algebra question: "Given A and B two square matrices of order n, such that det(A+X)=det(B+X) for all matrix X of order n. Show that A=B." Thank you.
