using Arduino UNO

I have been trying to use the help but unable to access it.
My question is I have been trying to use the servo.pde but I cannot compile it until I have inserted the '#include <math.h>' at the begining before it compiles. I am also having trouble with controling a servo of any kind.
Can anybody help?

Where did you get servo.pde? I don't think it's part of Arduino 0.22.

I cannot compile it until I have inserted the '#include <math.h>'

Using linux?
This (or something very similar) is a known problem using some of the newer avr-gcc and avr-libc packages under linux.
