The 1/8 circle comments ... sin (45) = cos (45) = (sqrt(2))/2 = approx 0.707. 45 degrees is 1/8 of a circle. Click to expand... I think we sometimes forget that cos(ωt) isn't just a triginometric function, but rather a circular triginometric function when discussing standard AC voltage and current. Hence...
