Well...I'm not sure what the first part is really, but that sucker is a sine wave with an amplitude of 4, a perod of 2pi/7 and a horizontal shift to the right of pi/2.
Should reproduction be be considered a basic human right?
Only if u can find an algorithm for that, Merlin :)
wouldn't this be a an integral?

Corina Marinescu : Ha! I'll work on it, but proof might take testing all the possible inputs. ;-)
you have to calculate the derivative, then replace X with 0It's kinda coool :D
Meh, if this would be as a captcha i'd probably never visit that site again...
28 cos (7x - Pi/2) evaluated at x=0, which is 0.
Be extremely lazy and notice that sin(-pi/2) is the bottom of a trough. The gradient there is zero.
I too thought it was 28*cos(-Pi/2) = 0Wolfram Alpha shows a different derivative, same answer thoughhttp://www.wolframalpha.com/input/?i=d%2Fdx%284sin%287x-Pi%2F2%29%29
Michael DankoIt's the same derivative.28cos(7x-PI/2) = 28sin(7x)sin and cos are just shifted versions of each other.
screw the sign up!!!
The concept is interesting---a capchka that keeps the riff-raff out.
This derivative = with the number of attempts u tried to sign in. It's a good trick ;)
Such a troll website... xD
Awesome!
