I would like to use some of math related function calls like pow, sin, sqrt...
But it seems math function doesn't work with SDK.
Either #include<math.h> on user_main or -lm on the Linker doesn't work too.
Do you have any idea to work them out?

What math functions would you like, How fast do they need to be?
Functions like Sin I think is 1 = x^2 + y^2 so I think if you take an argument you just do 1 - (arg)^2 = Value then SquareRoot that I think. Sorry I took trig like a year ago and it's already gone XD
