May 17	revised	Efficient way to solve equal sums $x_1^k+x_2^k+\dots+x_5^k=y_1^k+y_2^k+\dots+y_5^k$ with Mathematica? added 235 characters in body

May 16	comment	How to generate characters by a function which works like the Esc + a + ESC @Mr.Wizard You're welcome to improve it. It's definitely a bit rough around the edges at the moment.

May 16	revised	Generating partitions of a set with a specified size of the parts formatting of code
May 16	comment	Generating partitions of a set with a specified size of the parts Isn't there just one result, given by `Partition[myList, 2]`?
May 16	comment	Rationalizing Denominators with Radicals This is a site for doing stuff by Mathematica. Maybe you are looking for this. But in any case you can just multiply the numerator and denominator by $\sqrt(n+1)$.

May 11	comment	Prandtl-Meyer function Looks like you might have use `FindRoot` to get a numerical solution (`M2 -> 3.22983`).

Apr 23	answered	How can I create a new tables out of a table and plot it
Apr 19	comment	Determine the Number of Lines in a Text File As written, the code is reading char by char. Who knows if the underlying implementation is reading in more efficient chunks? I agree that C++ I/O is a bit disappointing (and not the easiest to use either!). I might go buy a solid state drive to compensate.

Apr 18	comment	Find point at which equation stops having roots (if it exists) The help tells you how to go from the generalised incomplete gamma function to the incomplete gamma function. Then you could just evaluate the integral directly to get the rest. Or many pages (such as mathworld) give the identity for integer arguments.

Apr 17	comment	Find point at which equation stops having roots (if it exists) Or more precisely for b > 6.88164.
Apr 17	comment	Find point at which equation stops having roots (if it exists) Actually you can have roots at negative M values for b > 2.
Apr 17	comment	Find point at which equation stops having roots (if it exists) That's the message indicating that there probably isn't a root. Also, I vote for b = 2.
