							  Some basic concepts of Mathematics
  (that we will frequently use.. read this section of
  your book carefully)



Functions

Variables ..Discrete and Continuous (based on nature of a variable
taking values)..examples in Economics?

-dependent variable and independent variable (based on
relationship)..examples? Little bit problematic sometimes?

Positive relationship – negative relationship


 straight line Vs Curved lines

Slope as a measurement of effect of a change in one variable..
some kind of ‘partial’ sense (more on higher level courses)
Continued..

 What happens when any other independent variables
  change? …idea of ‘Shift’ ?

 Shifts Vs Movements along the line

 Solving equations

 No more on Computer – let’s use the blackboard.
