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 (from pre-, 'beforehand'). Schools often distinguish between algebra and trigonometry as two separate parts of the coursework. [1]
