Dont know if this is the right forum for this question, let me know if its not! Im designing a car and i need a 50 litre fuel tank. Can anyone tell me what the dimensions of the fuel tank would need to be?

oh yeah, sorry about that, didnt think it looked right!. like i said its been a long hard day! thank you for the help i will try a few more make sure i got it.

ok, let me see if i have got this right, take the same matrix again but this time with an eigenvalue of 4 so you get [3x,5x+4y,3x+6y+z] again but this time it has to equal to 4 3x = 4x 5x+4y = 4y 3x+6y+z = 4z so the first gives x=1.3 the second gives y=0 and the third gives z=1.3...

yeah sorry its not that clear is it, i meant the three terms that make up the eigenvector, i can get eigenvalues alright. take for example the matrix that bracy posted how did you get the 1 -5 -13.5 i can get the equations out of the matrix ok but then get stuck

This is probably going to make me sound really stupid, but as this is my first post go easy on me! Im abit stuck on working out eigenvectors for 3 by 3 matrices, i get confused when trying to get the realtionships between the three values. Hope that makes sense!
