Hey all - sorry to be begging for your guys’ vote yet again.
A team I’m part of at school worked from 6am Saturday Oct.13 till past 3am Sunday morning to finish our video for the Insomnia Film Festival. The contest this time determines their winner entirely on PUBLIC rating, so we need as many people as possible to rate the video full score.

- Go to the Insomnia Film Gallery and find the following videos: Unwanted Company
- Rate it accordingly (excellent prefered ). You will need to be logged into an Apple account; if you don’t have one, make one! We spent 21 hours on this; you can spare a few minutes of your time please?

Tell everyone you know to vote (including family members) - the contest specifically suggests having all friends and family to EACH create an account and vote!

Thanks all!

For the unwary - there’s been a new Amazon spoof email supposedly asking you to verify your account ownership at Amazon. It may seem very authentic (has proper recipient info + sender email etc). The links are even displayed as “amazon.com”, but actually clicking it would lead to a completely different site (the page just looks like Amazon). Just something to keep a heads up on.

For the curious, here is what the email stated:

Finally studying Calculus - might be a surprise to a few of you who don’t know me that well. The teacher went through with some overly long processes on how to find the derivatives; for those interested, I also wrote a program to find/estimate the derivative (check your work? ).

Of course, it will not be 100% accurate (answers are in decimal). It will not determine whether derivatives exist or not (it assumes they do) and it will not find derivatives of infinite slope (it should return a 1/0 error though, which can be assumed to be infinite). Finally, a few rarer functions may have sign switches, so I’ve added an Apply +/- option for these cases.

All the math tools on the site now accept trig, powers, and roots.
