thanks to both.

only 2 vectors before and after going through T

where did the theta come from? usually when ure dealing with trig there are formulas u just need to accept and not dwell too much on. if abc are abitrary then = 1 and u have sinx + cosx = sin(x+theta) not seen this formula ever unless u made a mistake somehwere in writing it.

a R^4 --> R^3 Transformer is a 3X4 Matrix, i only know 2 values of 2 linearly independent vectors after going through T. Can i calculate T or do i need more information?

well the point is that we have gotten a lot of tech and science from studying animals. as more and more animals die due to pollution animals that we haven't even discovered yet could die before we every studying it. what if an animal exists that moves in the 4th dimension but it got killed off...
