i'm thinking that trig functions are like vector constants when used as expressions.

Like, y=cos^2x+3, or y=cosx/sinx

I'm meaning to talk about what's meant by a trig function is just a number and how trig is used beyong right triangle problems.

No, trig functions are like scalar functions (they are scalar functions). WHY do you think they have anything to do with "vector constants" (by which I presume you mean "constant vectors")? It is true that if x is the angle a 2-dimensional vector makes with the x-axis then its components are multiples of cos x and sin x but that doesn't mean that trig functions are "like vector constants". In what sense are your examples, y= cos2x+ 3 and y= cos x/sin x, "like vector constants"?
