This module aims to extend the material from MAS110. The central aims of this course will be to learn how to interpret the geometry of functions with more than one variable, solve systems of linear equations, and use calculus to understand the graphs of functions with several variables and the volumes that they bound. Material covered will include, but is not limited to, plane and solid geometry, matrix multiplication, linear equations, Gaussian elimination, graphs and level sets of functions with two variables, partial derivatives, volumes, and double integrals.
Prerequisites: MAS110 (Mathematics Core I)
The following modules have this module as a prerequisite:
|MAS112||Vectors and Mechanics|
|MAS211||Advanced Calculus and Linear Algebra|
- Basic plane geometry in 2 and 3 dimensions; solution of simultaneous equations, both geometrically as intersections of planes, and algebraically via Gaussian reduction.
- Matrices: introduction; interpretation as linear maps and the multiplication rule; determinants; eigenvalues and eigenvectors;
- Functions of two variables and partial differentiation; the Taylor series; tangents and normals; Jacobians.
- Multivariable calculus: further partial differentiation and the Chain rule; integration as area under a graph; two-dimensional integration; double integrals.
- To demonstrate techniques for representing lines and conics using co-ordinate geometry.
- To study systematic ways of solving simultaneous equations.
- To introduce matrices and matrix arithmetic.
- To develop students' skills in the solution of problems in matrix algebra and co-ordinate geometry.
- To introduce the ideas of determinants, eigenvalues and eigenvectors.
- To introduce series.
- To introduce the basic techniques of calculus of functions of more than one variable, and to gain expertise in calculating partial derivatives and double integrals, and in using the Chain Rule.
