If this is so, how is it that occassionally i crack an egg open that has blood in it? It seems to me that the blood couldn't begin development unless the egg is fertilized.

I feel retarded asking this, since there must be something extremely obvious that I'm missing. But I can't think of anything wrong with my logic:

the derivative of sin(x) = cos(x)

therefore, the derivative of sin(5) = cos(5) [x = 5, in this case]
the derivative of sin(10) = cos(10) [x = 10, in this case]
the derivative of sin(20) = cos(20) [x = 20, in this case]
the derivative of sin(100) = cos(100) [x = 100, in this case]

according to the chain rule, the derivative of sin(2x) = 2cos(2x); we could then say:

the derivative of sin(5) = 2.5cos(5) [x = 2.5, in this case]
the derivative of sin(10) = 5cos(10) [x = 5, in this case]
the derivative of sin(20) = 10cos(20) [x = 10, in this case]
the derivative of sin(100) = 50cos(100) [x = 50, in this case]

This is inconsistent with the above. What gives?
