3. 3 Text books Required:
Bradley & Patton’s Essential Mathematics for Economics & Business and Black et al Australasian Business Statistics,
Other useful books:
Gary Koop (2000 or 05) Analysis of Economic Data (good for topics 5-9)
Mike Rosser (2003) Basic Mathematics for Economists.
Dowling ET 2nd ed Introduction to Mathematical Economics
Computer program:
Excel (main program for whole paper)
4. 4 Expected Prior knowledge Prerequisites did require some knowledge of introductory Economics and Statistics
If you don’t have the required background then you need to put in some extra work
If you have never studied Economics before, then acquire an introductory textbook that covers both Macro & Micro topics.
5. 5 Topic 1: Calculus Aim to show how calculus can be used in Economics & finance
Study effect of a small change in one variable on other variables: eg. Marginal values
Help find optimal or maximum values : optimisation
Elasticities or effect of % changes in 1 variable on another
6. 6 References

Dowling Chaps 3-9
Objectives:
Reminder of basic rules of differentiation
Apply to single variable functions
Then to multivariable functions
Show economic & finance applications
7. 7 Definition Differentiation : Concerned with measuring the effect on the value of a function when there is an infinitely small change in the value of a variable in the function
Eg. How much does D or S change as prices drop?
Or what is the marginal propensity to consume at various income levels?
8. 8 So what have we measured? The slope of a line at a particular point on the line
This is also known as the first derivative:
Effectively measuring the slope or gradient of Y at a particular value Xi
If y = f(x) then
Also shown as f ‘ (x)
9. 9 Which Functions can be differentiated? A function can only be differentiated if it is continuous at that point and has an unique tangent at that point
So lines must have no gaps or holes or sharp turning points
Many econ & Finance functions are suitable
E.g. TR = 80q –3q2
TC = 2.5q3 –13q2 +50q +12
Next look at rules of Differentiation.
