who can help me with Linear Algebra and eigenvectors?

Has any1 got tips for coping under exam conditions. Anxiety is bad when ever it happens, but when you have several 2 hour exams coming up that count for a large part of your degree, you really dont want to be dealing with anxiety as well as trying to get a good grade! If Anybody has any tips on controlling anxiety and coping within an exam, I would love to hear about it!

Cheers in advance

I hate to use this thread in the way it was intended, but could anyone suggest how to find the first crossover point between the integral of e^(-x^2)+sin(x/12pi) and the integral of cos(x-x^2)^(xsin(lnx))?

I'm not exactly sure what you mean by crossover point, but if it is just where the two curves intersect, the would it be possible to plot them to find where they intersect? Or set them equal to each other and solve for x...I'm guessing this isn't as simple as that. By the way, that second integral is possibly the nastiest one I have ever seen.

The crossover point is where the weight of a function with a lower initial value (f(0)) surpasses the weight of a function with a higher initial value (g(0)). So, in this case, the intersection of the second integrals.
I concur on the nasty bit. My teacher is somewhat sadistic. I asked her about it and she said the e^(-x^2) part is called the Hearth Function or something like that and that it can't be integrated (or at least, that is what I gleaned), but past a certain point, its integral can be approximated by integrating 1/x^2. I suppose I could try the graphing approach, provided my calculator or winplot can handle it, but the problem is not from a solve-by-graphing section, so I'm sure it's supposed to be solved exactly by non-graphic means. As for the second integral, I don't even know where to begin.

Probably doesn't matter anymore, but the only way i can think to solve that would be through graphing it...it's probably possible to write a program to iterate until the equations are approximately equal as well, and get a point from that. I went ahead and tried to get the double integral of those functions in derive...the first one could be integrated, but had an error function in it. Derive couldn't integrate the second one at all...so i have no idea, that problem just sucks.

On Thursday, I've got my English GCSE exam on Romeo and Juliet and I'm dreading it!

O Romeo, Romeo! wherefore art thou Romeo? URGH!!! :evil:

I'm studying for a Bachelor of Science degree in Psychology. In my final year. Have 6 final exams in May. Each exam 2 hours long and have to answer 2 essay questions. Dreading it! Lol.

I'm 3rd year physio, 2 years to go including this one. I'm kind of scared though i don't know if i'll be able to do it. You kind of have to have some kind of communication skills to be a physio!
