Questionnaire

What does the letter 'c' mean to you?

a. It's the initial of someone I know and/or love.

b. It represents the speed of light in a vacuum, for example in the famous equation E=mc2.

c. It represents the constant of integration, necessary because the derivative of any constant function is zero.

d. It represents the number that comes before C++.

d. It represents cytosine, a nucleobase in DNA and RNA.

e. It is the chemical symbol for carbon.

f. It's a roman numeral.

g. It is a large body of saltwater.

h. It stands for Celsius, or centigrade.

i. It stands for Coulomb, the SI unit of electric charge.

j. It represents the third choice in this questionnaire, after choices a and b.

k. It was my favourite guest star on Sesame Street.

l. None of the above (please specify).

Um, sort of k

as in

'C is for cookie that's good enough to eat'

Which is a pretty good indicator of the 'chick's intelligence level.

Sorry for dropping the intelligence quotient by several dozen points.

Happy New Year!

Um, I don't understand "c.". Nor "i". Sigh.

C is for cat. Come on, how'd you miss that one??

Darn Roadchick used my answer! 'C is for cookie' though I thought it was 'good enough for me.' Oh, heck, Michelle has my second answer! OK, I'm sticking with my number one answer, anyway: Cookie, cookie, cookie starts with C.

Hope your New Year is charming (sorry that's the only positive 'c' adjective that comes to mind right now!)

@Roadchick: Quite. This was an oasis of intellectualism until you came along. Hmph. ;-)

@Tinker: Cool. :-)

@Michelle: Okay:

Integration is simply the process of taking an expression, A, and finding the expression, B, which when differentiated results in A. Exactly what integration and differentiation are doesn't matter. All you need to know is that when any constant value (ie. 3, -7, 0 etc. as opposed to 3x or y squared) is differentiated it becomes zero. This means that when differentiating an expression any constant values are lost, and when we run the process backwards (integration) we can't know what they were (except by performing further mathematics based on other sources of information). We represent the unknown constants of expression B with the letter 'c'.

And the Coulomb is simply the unit that scientists use to measure electric charge, just as the kilogram is the unit they use to measure mass, or the second to measure time.

And no, C is not for cat. :-P
