@DaveL.Renfro I appreciate the historical detail.

comment How does one 'correct' a table that doesn't add up to $100\%$?
@GlenTheUdderboat, this makes sense. Thanks for clarifying this.

Why not distribute the error evenly to every value?

comment Find the area between the functions
Specify the desired area accurately so that you can get the correct answer. The area under the square root function alone is different (larger) from the area enclosed by the intersection of the 2 curves, hence, the answer will be different.

comment Show that $f \equiv 0$
@Seth, thanks again, however, in this case it still won't make a difference, never mind, I was just curious.

comment Show that $f \equiv 0$
@Seth, thanks for your explanation, but $f(x)= t(x-0.5)$ would still give the same zero result. What am I missing?

comment Show that $f \equiv 0$
Just wondering about $f(x)=(x-0.5)$, the integral results in zero in the specified interval but f is not identical to zero.

comment How to efficiently calculate $ax+b$ once I know $a$ and $b$?
if values x are iterated in sequence such as $x=0,1,2,...,n$, you could use $y_{n}= a+ y_{n-1} $where $y(0)=b$

comment Visually stunning math concepts which are easy to explain
One of the proofs of the geometric series summ at: www41.homepage.villanova.edu/robert.styer/Bouncingball/… (see Fig. 4), it may interest you.

@GrahamKemp, You are correct...I was hasty.

comment The proof of $e^x < x + e^{x^2}$
May be you could try to put $y=e^x$ and assume the opposite, solve the degree 2 equation and base your proof accordingly.

comment On the arrangement of digits on a dice
Thanks for the answer. I some how feel that the sum of numbers resulting from independent throws of the dice (or the throw of 2 such dice and summing the value on their face) is biased because the arrangement of numbers follow a pattern and are not random. However, it looks like this is not true.
