edit not DC but AC, please help :)

- January 25th 2008, 05:23 AMJBsweAC problem
In a AC circet the current is i=i*sinWt where i=2.0*10^-3 and W=2pi*f and f=50Hz. i=i the second i has a little hat on it, dont know the symbol

I'am to write a diagram where the interval

0s<(or equal to)t<(or equal to)0.02s

I wrote a diagram from these values i found, can someone please check and see if i did the math correctly, am a little unsure if i should have my calc set to degree's or rads

i=2.0*10^3*sin(2pi*0*50) = 0

i=2.0*10^3*sin(2pi*0.01*50) = 1.1

i=2.0*10^3*sin(2pi*0.02*50) = 2.2
