Section 13 LHopitals Rule
Derivatives are defined using limits. Here we have an application where derivatives
are used to find limits.
13.1 LHopitals Rule for Limit at a Point
Suppose we are interested in finding
f ( x)
g ( x)
lim x a

Section 8
Derivatives
It is a fundamental task in many mathematical disciplines to find the rate of change of
a function f ( x) at some given point a .
In an earlier example, we were
interested in finding out the equation
of the tangent to the function g(

Elasticities
Economic analysis frequently focuses on elasticities the percentage change in one
variable that results from a certain percentage change in another variable: price

17.1 General Idea and Some Definitions
We have been studying functions of one variable y f ( x) . More realistic situations
usually require modeling a variable as being determined by two or more other
variables.

19.1 The Chain Rule
Suppose we have a function of n variables
y F ( x1 , x2 ,., xn ) ,
where each of the arguments is itself a function of m variables t1 , t2 , , tm , i.e.,

Matrix Algebra: Definitions and Basic Operations
Definitions
Analyzing economic models often involve working with large sets of linear
equations. Matrix algebra provides a set of tools for dealing with such objects.

Properties of Determinants
From Cramers Rule, we learnt that a system of n linear equations in n unknowns
will have a unique solution only when the determinant of the coefficient matrix is not
zero. When will the determinant of a matrix be ze

Implicit Differentiation
14.1 General Idea
Example 14.1.1 Consider the equation

whose graph is given below. Clearly, this equation defines a function y g ( x) such
that [ g ( x)]3 3x 2 [ g ( x)] 13 for all x .
