not playing?

2:14 "How did your computation go?" It must be a joke, I'm not a computer! She gave us so little time that I even couldn't get for a piece of paper…ahahaha

Definitely something I never had in linear algebra. The concept is clear, and the geometry makes it so.

mistake?? im getting -64.333 for 2nd determinant??

• October 9, 2013 at 8:40 pm

You probably forgot the negative sign for the 199 in the third row…

Indeed I did, thanks Riley

I should rather like to see the premise of the lecture proven.
That the volume is equal to the determinant.

Always love you teacher.

cute…….oh I mean very clear definition of determinant geometrically

• February 23, 2017 at 11:11 am

she and ben have the best explanation.

• February 26, 2017 at 11:00 am

very clear explanation. thanks.

that would only be true if (A1*A2 = A3*k), in other words, you're trying to compute the area of a romboid using the formula for the rectangle.

Is there a mistake at 10:54 where she mistakenly wrote -199 as 199 in the determinant?

• May 19, 2017 at 7:59 am

2 times -100 is exactly -201 .. when she say EXACTLY.. my ears started to bleed

• June 15, 2017 at 9:12 pm

i'm getting 52 as my seccond determinant: ((3*104)-(199*0))/6= 312/6 = 52…am i calculating the Det. wrong?

why do i feel like my iit jee faculties teach better than many mit teachers…am i the only one here who feels so
