Most colleges and high schools teach precalculus. However, I find that high schools, in particular, cover most precalculus topics in a course titled algebra 2 and trigonometry. So, my question is, why is precalculus needed anyway?

precalculus is more of a combination of trigonometry and functional analysis beyond that covered in algebra 2.
in fact, before it was called precalculus, the requisite courses were a semester of trigonometry and another semester course called functional analysis/analytical geometry.
