It is very important that you attend your tutorials!! Tutorials commence on Friday 4th of March That is this week. My Office Hours are: Monday 3.15 - 4.15 Wednesday 11.00 - 12.00 Friday 1.10 - 2.10 I may also be there at other times - drop by and see.

6
Alternative Help You can also approach Dr Sanming Zhou Room 146, Richard Berry Building Consultation hours are on the web http://www.ms.unimelb.edu.au/~dmk/620-161 There will also be a roster of tutors on duty. Consult the timetable in the Mathematics and Statistics Learning Centre. Consultation sessions will commence in Week 3.

Your Free Orange Book Detailed course information 11 Example Sheets You should work through an average of 1 sheet per week Details of homework to be handed in for correction Answers (not full solutions) to example sheets Previous exam papers and answers Sample mid-semester test Your orange book is an integral part of the tutorial system. Please ensure that you always bring it to class with you.

AssessmentAssessment 1.Final Exam (3 hours) 2.Mid-semester test (Monday 18th April) 3.Assignments (10 weekly assignments) Final Mark: Either: Test (15%) +Exam (75%) +Homework(10%) Or: Exam (90%) +Homework (10%)

Access to additional material Copies of lecture material will be available on the website at the end of each week. Reference Text: R. A. Barnett & M. R. Ziegler Applied Mathematics for Business, Economics, Life Sciences and Social Sciences. (Eds. 6,7 or 8) Course Aims To refine and extend knowledge and skills already obtained in VCE. To introduce new concepts particularly linear algebra and multivariate ideas. To appreciate how these ideas can be used in practical situations.

10
Outline of Topics 1.Linear Equations 2.Linear Programming (graphs) 3.Linear Programming (simplex) 4.Dual (LP), Logs/Exps 5.**Functions and Derivatives (one variable) 6.**Implicit differentiation 7.Optimization (one variable) 8.Partial Derivatives 9.Optimization (two variables) 10.Complex Numbers 11.Differential Equations

11
1.Linear Equations Objectives: 1.Revise the equation of a straight line. 2. (i) Algebraic solution for system of simultaneous equations (ii) Geometric interpretation 3. Introduction to Gaussian elimination Refs: B&Z 4.1 and 4.2

12
We can represent any line in the plane by the equation where the ordered pair (0, b) represents the y-intercept, (-b/a, 0) represents the x-intercept and a is the slope of the line. Example 1: 2 4 6 6 -2/3 x y (1, 5) (So a=3 and b=2) (So a=-1 and b=6)

13
A system of equations is a set of equations that we wish to solve simultaneously. Geometrically, this corresponds to the intersection points of the lines represented by the system. Example 1 (continued): (You can check this for yourself by substitution!!) The simultaneous system has solution x=1, y=5. 2 4 6 6 -2/3 x y (1, 5)

14
Formal (algebraic solution) We first rewrite the equations with variables on the left and constant terms on the right. System represents two lines in the plane. (A)Interchange order of equations : a different system with the same solution. (B) Multiply one equation by a non-zero constant.

15
(C) Add a multiple of one equation to another. (B) Multiply one equation by a non-zero Constant. So The solution is x=1 and y=5. 2 4 6 6 - 2/3 x y (1, 5)

16
What operations did we use to produce equivalent systems with the same solution? A. Interchange order of the equations. B. Multiply one equation by a non-zero constant. C. Add a multiple of one equation to another. A shorthand notation allows us to avoid writing x, y in every step of our calculation. Using matrix notation and the operations (A), (B) and (C) we can perform the previous calculation much more efficiently.
