Jun 19, 2011 - I did the same on my adobe flash software. After I put all the pieces together as in the second picture, I've got a hole in the middle the whole way.

menthol5 Says:

Jul 31, 2011 - you are not correct. Derivatives can not be greater than one. It is the slope of the line after all. For red/blue slope = .3846 (right) on the Left there are two slopes; .375 & .400. They messed with the slope to make it appear what they have shown is true - Not!

Aug 25, 2011 - @isak885exactly! nureddin has erred in the slopes. the 13*5 rectangle isn't a rectangle at all! i've tried this with precision-cut paper shapes. the area of the quadrilateral should be ½*13*5 + ½*12.6*5. by simple ruler measurement in cms.

Sep 14, 2011 - Derivatives can't be greater than 1? What sort of school did you learn math from?Very simple counterexample, take equation of line y=5x. Derivative of that is 5. Derivatives can take any value or be any function, or hell, not be functions at all, depending on what you're taking the derivative of.

Oct 30, 2011 - 0:22 The square's sides don't coincide exactly. Therefore you can't simply do 5*13. You can also see that there's a lil bit missing. On top of the resulting "rectangle". The area of that little missing part is 1.

Oct 30, 2011 - Derivatives cannot be greater than one?....

raydredX Says:

Oct 30, 2011 - Would you say that the derivative OF A FUNCTION can be not a function? I'm curious I disagree and I think I could prove it but I may be missing something.

Oct 30, 2011 - This is a visual trick the angle of the two inclines is not the same one is 2/5 and one is 3/8 so the diagonals are not a straight line and creat a ramboid whose surface area is equal to one.. Therefore 8x8 is not equal to the 5x13.

Nov 15, 2011 - middle bit have overlap, not a math trick, just an illusion

andreirocks1992 Says:

Nov 19, 2011 - just as everyone pointed out, in one part of the figure, the diagonal goes 2.5 squares right and for 1 square up, and in another part, it goes 3 right for 1 up, therefore it's not the same line

speng120 Says:

Dec 25, 2011 - Put simply looking at the square, the orange and blue shapes have the slope of 2 across for 5 up whereas the red and green shapes have slope 8 across for 3 up. 5/2 is not 8/3 henceforth impossible

pafeuvip Says:

Dec 26, 2011 - that's right,Thales' theorem :)

revison97 Says:

Dec 28, 2011 - that is just parallelogram .It look like rectangle but angles are not right.and 64/13= 4,(923076) so angles are not so different as in rectangle
