Help with Matrix problemI do not now how to do these types of problems. Could somebody point me in the right direction? Find the matrix A such that A[ 1 0 ] = [ -5 -4] [ -1 4] = [ 7 12] hint: let A = [a b] [c d] |

Re: Help with Matrix problemDo you know how to do matrix multiplication? Set this equal to the given matrix, then solve by setting corresponding elements equal to each other. |

I get to here: Then: In equation form is a = -5 b= -4 -a + 4c = 7 -b +4d = 12 Solving for c and d gives a = -5 b = -4 c = .5 d = d = 2 Is this correct? I am new to this, just trying to figure it out by following along in a book. |

Re: Help with Matrix problem4b = -4 a - b = -5 4d = 12 c - d = 7 |

Re: Help with Matrix problemThanks for the replies everyone, this is really helpful and makes sense now. This forum is fantastic, it is hard to "teach" yourself from a book when you don't know what to do, thanks again for the help I have a feeling I am going to be asking a lot of questions here. Hope you all don't get annoyed with me lol. |
