Notes

Some (not all) parts of the course notes will be in the form of a handout or will be available here. All will be in PDF format and require a programme such as Adobe Acrobat Reader to read them.

Refer also to the textbooks.

Chapter 1. Vectors
(Chapter 11 in Anton's Calculus.) This deals with vectors from a geometrical point of view (arrows) first. Then a more algebraic approach (with components). Equations of lines and planes in space. Cross products. Basic ideas about higher dimensions.
Chapter 2. Exponential and Log functions
(Chapter 6 in Anton's Calculus.) This deals with the exponential function $\exp(x) = e^x$ and its inverse the natural logarithm function $\ln x$. Also other functions, the inverse trigonometric functions and the hyperbolic functions.
Chapter 3. Techniques of integration
(Chapter 7 in Anton's Calculus.) We recall first what integration is and the technique of substitution. Then integration by parts, trigonometric integrals (powers of $\sin x$ times powers of $\cos x$), inverse trig substitutions, partial fractions. Then improper integrals and how computers can evaluate integrals (computer algebra systems and basic ideas for numerical evaluation of definite integrals).
Chapter 4. Differential equations
(Chapter 8 in Anton's Calculus.) Besides some general explanations about what differential equations are and where they arise, we just consider two kinds that can be solved easily: variables separable and first order linear (constant coefficient).
Chapter 5. Infinite series
(Chapter 9 in Anton's Calculus.) Sequences and their limits. Series, some tests for convergence. Power series.
Chapter 6. Linear equations
(In Chapter 1 of Anton, Linear algebra) Gaussian elimnation and Gauss-Jordan elimination.
Chapter 7. Matrices
(In Chapter 1 of Anton, Linear algebra) Matrices, matrix multiplication, inverse matrices, elementary matrices and their connection to elementary row operations, finding inverses, special matrices (diagonal, triangular, symmetric, nilpotent), trace of a square matrix.
Chapter 8. Determinants
(In Chapter 2 of Anton, Linear algebra) Determinants by cofactor expansions. Calculation by row reduction. Cramer's rule.
