Precalculus, a transitional mathematics course and not a discrete field, is designed to prepare students to learn calculus by presenting aspects of algebra and trigonometry through a calculus lens. Algebra focuses on variables in number and number sets with analysis on imaginary and complex numbers and mathematical functions associated with these. Some of the algebraic concepts explored in precalculus include slopes, graphs, polynomials, linear functions, and square roots. Trigonometry focuses on evaluation of triangles and lines and angles thereof. Some trigonometric concepts associated with precalculus include slopes, tangents, reflections and shifts, parabolas, rational functions, matrices, exponents, and logarithms. Precalculus functions, just as with calculus functions, are used in various scientific and mathematic fields, like chemistry, biology, and economics.
