how do I find the range of the function f(x)=1/sqrt(-[(x-5)^2-9]) ?? I know that it's minimum is at x=5 y=1/3... but what is its maximum?

anyone knows how to reproduce the Harry Potter and the Chamber of Secrets disappearing ink in the diary trick?
here should be a photo of Riddle's Diary, but it seems to be broken..

I have to do the same.. write in a copy book, then make the ink disappear somehow..
the first idea I got was to take a photo of the empty page, then record as I write on it, then play the movie and add some kind of fading to the empty page photo in the end.. but I still couldn't try that one, since my damn tripod seems to have been gone somewhere.. argh.. :@

school started yesterday, and - as per usual - our time table was screwed up again.. but never mind..
brought my laptop to school today, since i still didn't have the time to buy pens (and atm i don't even have money to do so.. i still didn't get the credit card i applied for like a week ago. why does a pen have to cost over $25, argh?!)..
tomorrow i'm gonna bring the usb cable for my cell, so i can use the internet there too.. we seem to have wcdma all around the city and hsdpa in some places.. that is, the mobile internet is quite friggin' awesome here.. and me loves that.
too bad i only have a 50 mb data plan.. *considers upgrading to 2 gb - once me has more money*

anyways.. me has 31 lessons a week in total, but 7 of those comes off since i passed a-levels on esl and french earlier this year (end of last school year).. and i'm still unsure if i'm gonna attend advanced maths (that would add 2 lessons..), cuz it's likely to be held in hungarian only..

as for my schoolmates, i still love them all.. school can be an entertaining place you like if you have a class like the one i have..

My camera's still screwed up, see http://www.flickr.com/photos/ebertek/
I have nothing to blog about; check http://twitter.com/ebertek , I update that quite often

So, dad was taken home last Friday (3rd) by an ambulance.. The professor got totally shocked when the ambulance and the doctor from Hungary arrived in the morning, as he asked the insurance to take dad home by plane.. Anyways, as he had no other choices, he had to let him home by ambulance.. We got home late in the night, after 11pm, and he was brought to a hospital here in Pécs..
He is still there during the mornings, but can come home after 4pm, and can also spend Friday-Sunday at home..
