Question

if possible compute: AB^T

don't understand this...

Answer 1

That sounds like a linear algebra problem. In future, you should post it here: http://openstudy.com/study?version=feed:join-study-group&referrer=mit%2018.06%20linear%20algebra,%20spring%202010&domain=ocw.mit.edu#/groups/MIT%2018.06%20Linear%20Algebra%2C%20Spring%202010

Right now, I'll need a little more information on A, B, and T.

Answer 2

Matrices?
B^T = transpose of B?!

Answer 3

If the ^T is supposed to mean "transpose", then it means something entirely different from if ^T is an exponential. Also, I need to know where the parenthesis are.

Answer 4

@Numb3r1 it will be correct in that situation too.

Answer 5

A times B transpose is not the same thing as (AB) transpose. Similarly, (AB) ^ T (as an exponential) is not the same as A (B^T).

Answer 6

ya it is ok now to.

Answer 7

(AB) transpose is B transpose times A transpose. (AB) transpose is A times B transpose. They are different. I can explain the same relationship for exponential, but they are not even remotely similar unless T equals one for the exponential.

Answer 8

the only information im given

Answer 9

The whole question?

Answer 10

the whole question is AB^T

Answer 11

compute if possible

Answer 12

(AB)^T my bad

Answer 13

Is the T just a small letter above (AB)?

Answer 14

t is the exponent

Answer 15

If it's a capital T, it probably means "transpose". In that case, the rule is probably in the book and the course you're taking, but I'll repeat it here: \[(AB)^{T} =B ^{T}A ^{T}\]

Answer 16

Im taking math for developers..book is confusing as hell.teacher doesn't really use the book becaus eof how confusing it is.
