Study Notes

Syllabus Selection Exam - Mathematics & Physics

  • Introduction: The exam covers fundamental topics in mathematics, physics, and selected first-year material, based on Dutch VWO curriculum.

Mathematics

  • Functions and Graphs: Candidates must recognize and construct compositions of standard functions, including polynomials, n-root functions, power functions, logarithms, exponentials, and trigonometric functions (sin(x), cos(x)). Analysis, sketching, and transformations of these functions, along with determining limits, domain, range, asymptotes, and symmetry, are required. Understanding and finding inverses of functions (and their compositions) is also essential.

  • Algebraic Solving: Manipulating expressions to isolate variables, substituting expressions into functions, simplifying expressions, and recognizing special products are key skills. Solving equations and inequalities involving standard functions, finding roots of functions (using factorization and the quadratic formula), and solving systems of linear equations are assessed.

Differential Calculus

  • Derivatives of standard functions: Candidates must know the derivatives of standard functions.

  • First and Second Derivatives: Calculating first and second derivatives, using the product, quotient, and chain rules. Evaluating locally increasing/decreasing behavior, extreme values, concavity/convexity, and inflection points through the use of derivatives is crucial.
