Pre-requisite(s): MA 2005

A) Several variables - Continuity and Partial Differentiation.

• Functions of several variables, graphical surface representations, limits and continuity, partial derivatives, higher order partials, plane tangent, linear approximation, small errors.

• Chain rule, polar coordinates, applications to some elementary PDEs.

• Critical points, second derivative test, some discussion of global global max/min.

• Taylor series and quadratic approximation.

B) Several variables - Multiple Integrals.
• Revision of definite integral as area under curve, approximated by rectangles. Double integral as volume, approximated by rectangular pillars.

• Iteration formulae for rectangles and for more general regions, change of order of integration via double integral.

• Change of variable in double integrals (with emphasis on polars).

• Triple integrals, cylindrical and spherical polar coordinates.

• Applications to volumes, moments and centres of mass.

C) Ordinary differential equations.
• Basic terminology, general solution, integral curves, initial and boundary conditions.

• First order ODEs: linear equations, separable equations, brief treatment of homogeneous and Bernoulli equations, applications (eg. population problems and mixing problems).

• Second order linear ODEs: basic theory for solution of equations with constant coefficients via CF + PI, applications; reduction of order and variation of parameters.

D) Introduction to computing software (4 practical sessions).
• Simple arithmetic, operations, variables, booleans, conditionals, functions, procedures, plotting, functions in two variables, contour plots, parametric plots, basic algebra, differentiation, integration, programming, loops.
