OK, I'm going to sound like that crazy lady that baths in her trailer park backyard for a minute here. When you swish a fly away from you do you think it's scared or irritated, and why is it that as soon as you get the fly swatter out the little bastards take off and hide? Sorry I've got this under science and mathematics, but really what was my option "pets"?

Let a and b be eal numbers.

Prove that |a-b| = |b-a|. (absolute values)

I proved it by cases (four), but I'm not sure whether I did it correctly or not. Please prove it if you can, I want to compare my answer and learn. Thanks.

My apartment has tremors and vibrations that feel like a small earthquake. It comes and goes, and my landlord and I have no idea what it is. We've checked with other tenants with respect to fans, A/C's, etc. We would like to measure the vibrations and feed it into a PC so that we try and get a better understanding of thigns. Any ideas on how to do this short of buying a seismograph? It wakes me up sometimes in the middle of the night as it shakes my bed, so I would like to fix this. And no we are not thinking of calling an Exorcist.

Im a electrical tech student.. and I have a multiple choice question, which I can't find any answers too, after searching the net several op-amp books in a local library...
If the Rf of a Non-inverting op-amp is shorted the output waveform would be...
Zero,
Clipped,
have the same shape and amp. as the input waveform
or smaller in amp. that the input waveform.

Im guessing have the same shape and amp.. any thoughts?
