PAU Applied Mathematics for Social Sciences II (Cantabria) study plan

PAU Applied Mathematics for Social Sciences II (Cantabria) · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Matrices and systems of linear equations

  • Perform matrix addition, scalar multiplication, and multiplication, verifying dimension compatibility.

  • Compute determinants of 2×2 and 3×3 matrices using cofactor expansion and the rule of Sarrus.

  • Calculate the inverse of a square matrix using the adjoint method and the Gauss-Jordan method.

  • Determine the rank of a matrix by reducing it to row echelon form.

  • Solve systems of linear equations using Cramer's rule, matrix inversion, and Gaussian elimination.

Your checkpoint

A one-page summary sheet listing the steps for each method, plus a set of 10 solved exercises (at least two per goal) with all intermediate work shown.

Week 2

Matrices and systems of linear equations

  • Classify a linear system as consistent or inconsistent using the Rouché–Capelli theorem.

  • Solve systems with one or more parameters, expressing the solution in terms of the parameter.

  • Model a word problem (e.g., mixture, investment, or production) as a system of linear equations and solve it.

  • Interpret the solution of a system in the context of the original problem, checking for feasibility constraints.

Your checkpoint

A set of 8 parameterized systems and 2 word problems, each solved completely with a written justification of the classification and interpretation of the solution.

Week 3

Linear programming

  • Formulate a linear programming problem from a verbal description, identifying decision variables, objective function, and constraints.

  • Graph the feasible region for a two-variable problem, including finding the vertices algebraically.

  • Solve linear programming problems graphically, including cases with unbounded regions and multiple optimal solutions.

  • Apply the simplex method to standard maximization problems with slack variables.

  • Interpret the optimal solution and the meaning of slack variables in context.

Your checkpoint

A portfolio of 5 fully worked linear programming problems: 3 solved graphically (with hand-drawn or plotted feasible regions) and 2 solved by the simplex method, each with a written interpretation of the optimal solution.

Week 4

Linear programming & Functions, limits and continuity

  • Solve integer and mixed-integer linear programming problems by branch and bound for small cases.

  • Compute limits of polynomial, rational, exponential, and logarithmic functions at finite points and at infinity.

  • Identify and classify discontinuities (removable, jump, infinite) from a function's expression.

  • Apply the intermediate value theorem to prove the existence of roots.

  • Determine the domain and range of functions involving radicals, logarithms, and absolute values.

Your checkpoint

A mixed problem set of 12 exercises (6 on linear programming including one integer case, 6 on limits and continuity) with complete solutions, plus a half-page concept map linking limits, continuity, and the intermediate value theorem.

Week 5

Differential calculus and its applications

  • Compute derivatives using the product, quotient, and chain rules.

  • Differentiate implicit and logarithmic functions.

  • Find equations of tangent lines and normal lines at a given point.

  • Apply the first and second derivative tests to determine intervals of increase/decrease and concavity, and to locate extrema and inflection points.

  • Solve optimization problems (e.g., maximizing area or minimizing cost) by setting up and differentiating an objective function.

Your checkpoint

A set of 10 derivative and optimization problems, including 2 full optimization word problems, each with a sketch of the relevant function and a clear argument for why the critical point gives the desired extremum.

Week 6

Differential calculus and its applications & Integral calculus and areas

  • Compute indefinite integrals using standard formulas, substitution, and integration by parts.

  • Apply the fundamental theorem of calculus to evaluate definite integrals.

  • Calculate the area between two curves, including choosing the correct integration limits.

  • Use the mean value theorem for integrals and interpret the average value of a function.

  • Solve applied problems involving areas (e.g., consumer and producer surplus, or profit over time).

Your checkpoint

A problem set of 10 integrals (5 indefinite, 5 definite) and 3 area problems, each with a graph of the region and a written explanation of the setup and evaluation.

Week 7

Probability and random variables

  • Apply the axioms of probability and the addition and multiplication rules to compute probabilities of events.

  • Use conditional probability, the law of total probability, and Bayes' theorem to solve problems.

  • Define discrete and continuous random variables, and compute their mean, variance, and standard deviation.

  • Work with the binomial and normal distributions, including standardization and use of tables.

  • Solve problems involving the normal approximation to the binomial distribution.

Your checkpoint
