That's odd. It's not running hot, so it's not a cooling issue (from what I can tell) but the computer should have a PSU powerful enough to power what they put inside it... and 400W does seem a little weak. Then again, manufacturers like to go with the minimum. However, it should still be fine. What other components do you have in there?
"Uhhh... I don't know if I want a subscription to |__________|. You know what, why don't you give me your home number and I'll call you back when I decide... what? Oh, you don't want to give me your home number? You don't want me calling your house? Oh ok - DON'T CALL ME EITHER!" CLICK!
With regards to the third problem, if you substitute cos(x) as u, then when everything cancels you end up with 1/u and the integral of that is log(u)... (we use log and ln interchangeably here). So then I substitute cos(x) for u again and I get -log|cos(x)| so I'm fairly certain that what I have all the way is right (I don't know if the + c is needed or not in this problem.)
Thing is, when you do the actual integration between the two points given (3c and sqrt(y)) I guess that I'm just going to have one bit LOONG answer with a lot of variables then? Something like this maybe:
Exactly my point. I guess you could relate it to the slower cars in a race being sometimes more of a hazard that the cars fighting for the lead. In fact, you go too slow, they take you off the track because it's too dangerous. Not quite the same thing, but you get my point.
Yeah - that's some nasty stuff going around. I know that these things can be dangerous, but I'm hoping for the worst. I'm in Virginia, in the mountains, so tornadoes and such aren't as likely, but I haven't seen a good thunderstorm in years now.
