You know what they say: the road to advanced mathematic courses is paved with precalculus textbooks. Precalculus - a preparatory course for calculus - explores real numbers, inequalities, vectors, and other concepts that build on algebraic equations. The discussions of algebra and trigonometry found in precalculus textbooks are invaluable precursors for students who intend to tackle higher math. Moving beyond precalculus, our comprehensive collection includes advanced calculus and applied calculus textbooks.
