It is never too late, and I mean never. I go to a community college, there is a dude who is 65 in my linear algebra class. He's older than my professor. Also their is a guy I work with who decided to get his FE by taking calculus and physics at a university. He started 2 years ago and he's 55...

Honestly, if you showed up to a somewhat public engineering firm and asked them what they did they would gladly tell you if they weren't busy. I intern myself for a governmental civil/mechanical department (transportation). If you caught an engineer who wasn't busy, they'd tell you their life story.

The A in my previous post is a 3x2, multiplied by a 2x1(v) so A = [1 1] [1 0] [0 1] v = [5] [4] Sorry I was using MATLAB notation with the semicolons. A is found by finding the standard matrix of a linear transformation from T(x,y) = (x+y,x,y). Essentially this A matrix is what you have...

I am also on the same problem. Part A asks to find T(v) using the standard matrix. T: R^2 --> R^3, T(x,y) = (x+y,x,y), v = (5,4) so A = [ 1 1 ; 1 0 ; 0 1 ] and Av = (9,5,4) which is the answer given in the back of the book. So since the problem basically asks you to...
