Compute the eigenvalues of a random-looking (but still integers) 4x4 matrix? Oh, it's sqrt(2), I probably didn't make an error in the calculation.
Then came the advanced physics / mechanics exam. It threw a wrench into our beautiful system. The results were just about anything, incredibly ugly, like the real world :yuck: :vomit:
You remind me of my university maths exam. In all the past papers, the eigenvalues came out to be round numbers. But in the real paper I sat, no matter how many times I tried to find my mistake, they didn't. I wasted hours of the exam on that.
It was the professor's final year before his retirement.
Turns out that was not a design goal of the real exam and basically nothing worked out to neat, small integer solutions - I probably would have hard failed without the calculator. I'm still sort of confused why prep materials and the real exam diverged so much.
