# Thread: Precalculus Taught in Different Courses

1. ## Precalculus Taught in Different Courses

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.

If that is the case, then what is the difference between precalculus and college algebra?

precalculus is a whole year course that includes trig ... college algebra is a single semester course dealing only with algebra.
