can anyone help?
your problem is, that [tabwrite] quantizes along the x-axis: writing to 2.1 or 2.9 is the same as writing to 2. so the value that is actually stored at each point is "sin((i+0.9)*2pi)" which is sin(i*2pi+phi) , with i = integer; since sin() wraps at 2pi you always have the same value.
try using *pi/180 instead of *2pi.
btw, for your example you need 2 externals, while none is necessary.
