My work is shown in first post now.

Homework Statement https://dl.dropbox.com/u/66988308/Capture.JPG Homework Equations V=rWThe Attempt at a Solution I tried to plug in the forumla , and algebras but I keep getting rc/rf as answer instead of rf/rc as the book says. Work: Vf=(rf)W W=Vf/rf W=Vc/rc Vc/rc = Vf/rf (Vc)(rf) = (Vf)...

Thanks for the replies, just what I needed Erland.

Im having trouble under stand the relationships between determinats, span, basis. Given a 3x3 matrix on R3 vector space. * If determinat is 0, it is linearly dependent, will NOT span R3, is NOT a basis of R3. , If determinant is non-zero, its linearly independent, will span R3, is a basis of...

Just solved it. thanks for the reply though. 1 1 1 a b c a^2 b^2 c^2 becomes 1 0 0 a b-a c-a a^2 (b^2-a^2) (c^2-a^2) then becomes (b-a)(c-a) times 1 0 0 a 1 1 a^2 b-a c-a then 1 0 0 a 1 0 a^2 b-a c-b det= 1 x 1 x(c-b) ( c-a) (b-a)

Homework Statement 1 1 1 a b c = (b-a)(c-a)(c-b) a^2 b^2 c^2 (above is a 3x3 matrix equaling to a equation) question:"Show by applying property of the determinant"Homework Equations N/AThe Attempt at a Solution read through the whole chapter of...

Thanks a lot, that was a good explanation.

Thanks for the reply. another question would be, gravity is a form of centripetal acceleration ? since they have the same units.

Is gravity a Uniformed Circular motion? I had this question for a while and i googled searched it but no results, I also did the readings which I do think it is. But in the readings , I never read the statement that says gravity is a form of uniformed circular motion. Can anyone explain why or...
