In [[mathematics education]], '''precalculus'''  is a course, or a set of courses, that includes [[algebra]] and [[trigonometry]] at a level that is designed to prepare students for the study of [[calculus]], thus the name precalculus. Schools often distinguish between algebra and trigonometry as two separate parts of the coursework.<ref>{{cite book |last=Cangelosi |first=J.
