...but are not straight lines? Consider the functions
y = sin(x) + 2 and y = sin(x) + .5
Both of these lines are graphically represented as sine curves with a period of 2? and an amplitude of 2, thus they will never intersect. The only difference is in their y-intercept determined by the +2 or +.5
I need to be able to describe the relationship that these lines have. Parallel lines do not intersect, but do they have to be literal "lines", or can "parallel" be used to represent a function as well? So are they simply called parallel, or is there a better term?
