Need help with matrix
I need help with solving the matrix, I googled but I just don't understand. Found a good site (http://www.purplemath.com/modules/mtrxinvr.htm) but my English isn't that great.
Re: Need help with matrix
I don't know about matrices, but this just looks like a simultaneous equation.
Why did the vector cross the road?
It wanted to be normal.
