Question

- into - is what?

Answer 1

i mean minus into minus

Answer 2

linear algebra? are you going over linear transformations?

Answer 3

yeah

Answer 4

ok, do you mean into or "onto"? i.e. one-to-one and "onto" linear transformations.

Answer 5

onto

Answer 6

onto linear transformations: T is onto if & only if the rank of T is equal to the dimension of W, where T:V-->W is a linear transformation...

Answer 7

basically every element in W has a preimage in V...

Answer 8

...does it make anymore sense? another way of saying it is that T is onto W when Wis equal to the range of T.

Answer 9

okay

Answer 10

good luck! little bit more abstract, so some find it a little dry & boring sometimes...

Answer 11

minus into minus is positive. Division of like signs are positive.

Answer 12

right. that's -/-... she stated that she was refering to "onto" which describes a linear transformation in linear algebra--that's why i asked before going any furhter...
