Here c denotes a constant which can vary from line to line.
Fix n and let c vary.
As we let t vary, f(t) describes a curve in M.
Within I, the function f varies <oscillates> by less than 1.
The idea is that C is fixed, but X and Y vary according to circumstances.
Then F varies smoothly in t.
The samples vary in length.
Note that m is permitted to vary with the number of inputs.
A number of authors have considered, in varying degrees of generality, the problem of determining......
