comment How to deal with Part in a function?
@EdMendes. I don't see any reason why traject can't be called in a Manipulate expression with α values supplied through a control such as an Animator, the default control type for Manipulate expressions that looks like a slider. Every function called in a Manipulate expression doesn't have to be define inside that expression; it only has to known to kernel at the time the Manipulate expression is evaluated.

comment How to deal with Part in a function?
@EdMendes. The vertical bar (|) is Alternative. The pattern f : (_Function | _Symbol) restricts the argument f to have a head that is either Symbol or Function. Presumably, when it is a symbol, that symbol will name a defined function. The head Function identifies any pure function. Placing this restriction on the first argument isn't fool-proof, but does catch many common errors.
