Optimistic as always I woke up today around 9am (and by wake up I mean that is the time I initially decided to hit the snooze button). The usual wake up routine, stick on the computer and the TV while generally slopping around for an hour. Enter the first disappointment of the day: my first windows 7 blue screen of death... I won't bore you on the details but suffice to say I won't be using NVidia Graphics Drivers anymore on my computer.
Got the 11:08 from Meldreth to Cambridge (and for the first time in the history of trains, this one was on time to the minute!) and arrived at college. Grabbed the pre-exam Subway that I have never been without and got stuck in to some casual revision (although someone had decided that this was a good day to play a Red Dwarf DVD for a lovely distraction). After going I don't believe it was that tough, confidently predicted myself a UMS of 80 (and for those not down with the exam lingo that's the lowest score possible to get an A). One question that really got me stuck was what is d2y/dx2 when y=tan(4x)... All I can say is for this, the first answer I got was 4 and the second missing number was 8. (No promises of them being correct although I would love to know what you got if you also took this exam.)
My 'things that arrived today' section; as most people who know me know, I am addicted to online shopping (particularly Play.com) and therefore daily deliveries often come my way with useless crap that seemed like a good idea that the time. I thought it might be fun to keep you updated on what comes through ye old postbox...
- Juno DVD, £2.99, Play.com - a fantastic DVD, couldn't possibly resist this for £2.99!
- Hama Star 62 Tripod, £12.99, Play.com Marketplace - I bought this with the intention of using it on my trip with the lovely girlfriend that is coming up soon so that, 1. There can actually be some photos with both of us in and 2. I don't have to give the camera that cost me about £150 to a complete stranger to achieve this.
A good start Aiden... My Blog is coming in the next few weeks... My first Win7 BSOD was when i installed it... but second time lucky :P. As I said i got 4 and 8 likewise... are you sure it was y=tan(4x)... as wolfram alpha says that goes to 32tan(4x)sec^2(4x)... don't think there was a sec^2 in the alleged answer format... Would like to know if we were right...
ReplyDeleteWindows 7 < Ubuntu. Or even XP.
ReplyDeleteAlso, I thought that q=32. That's what I got differentiating dy/dx = 4(1+tan^2(4x)).
Mike.
I think the point was that using the answer in the formula booklet, you could easily get the answer with sec^2(4x) but the point was to get it in the form: 'qy(1-y^2)' where q is the number to be discovered.
ReplyDeleteOne thing to say... you did not have a pre exam subway... that is all :)
ReplyDeleteOh yeah! It was a pre-exam tesco express trip! SEE! That's what lack of subway does to my memory! :D
ReplyDeletewhy do you have so much money
