Description
A large portion of this file is commented out, including the math_atan function which I wanted!
I have uncommented it, and commented out just the math_sin, math_cos and math_tan functions (already defined).
Is there a reason for this?
(BTW really appreciate this library!)

Hello David,
Thank you for using the STL.
The functions that are in comments
are the old trigonometric functions that used external libraries .dll (windows) or .so (unix/linux).
The problem with the dependency on external libraries
is that they were not included in some unix variants/versions.
Jeff Pilant added trigonometric functions that are 100% progress with no dependencies
using series http://en.wikipedia.org/wiki/Trigonometric_functions
Badian (b_i_h@ukr.net) also participated in the development of these functions
but like you said not all the functions were replaced.
I encourage you to finish and send me the rest of the 100% progress functions
together with the new functions you wrote to add to the STL project.
so everyone else who runs into the same problem could use your code.

Thanks, I see now. Would love to implement the inverse functions, but I'm no mathematician and don't understand the info I'm finding on the net..
Looks like I'll have to let the OS do the maths, while I work on satisfying clients..
