on how to see goniometric functions in space let be a linear function, like $$ \tag{1} y=x $$ onto that then another function, that includes the linear function like, increasing the number of dimensions $$ \tag{2} g(y(x)) = z $$ bc $$ y=x $$ can be expanded to $$ y(x) = x $$ so goes a simple function $$ \tag{3} z = g(y(x)) \in Z(g, y, x)$$ and you starting to form a changing system \(Z\) in, say, time...
