Hi zetafunc;
Hi;
I forgot about the reference... although regarding secondguessing, I have noticed that they repeat some questions from time to time, and I just found the e^A where A is a matrix question in an old STEP paper. So, it might be useful... although I'm just worried about being thrown into a new environment! What if I get completely stuck and get nowhere at the interview?
But at the moment I'm not supposed to have developed a preference yet  I'm still in the last year where there is pretty much a set syllabus everyone should be able to use. I am just worried because I was not able to get that solution...
Can you show me how to do this? Is this the same as matrix decomposition?
hi zetafunc,
Hi;
The time taken is related to your experience and what fields of math you prefer and major in. It only takes someone in computational mathematics 5 seconds to think of that since they use the Taylor's series every day and for darn near every problem.
Hi zetafunc.
