Table of contents
Preface
Programming in Java doesn't have to be dull and boring. In fact, it's
possible to have a lot of fun while programming in Java. This module wastaken from a series that concentrates on having fun while programming in
Java.

General discussion
The purpose of this module is to help you to understand how the
Fast Fourier Transform (FFT) algorithm works. In order to understand theFFT, you must first understand the Discrete Fourier Transform (DFT). I
explained how the DFT works in an earlier module titled
Fun with Java, How and Why Spectral Analysis Works .

U(x,y) = (x×y)1/2
find mu of x for y
U(x,y) = (xÃy)1/2
find mu of x for y

macroeconomic is the branch of economics which studies actions, scale, activities and behaviour of the aggregate economy as a whole.

difference between firm and industry
what's the difference between a firm and an industry
Abdul
firm is the unit which transform inputs to output where as industry contain combination of firms with similar production 😅😅

Suppose the demand function that a firm faces shifted from
Qd 120 3P
to
Qd 90 3P
and the supply function has shifted from
QS
20 2P
to
QS
10 2P .
a) Find the effect of this change on price and quantity.
b) Which of the changes in demand and supply is higher?

economics is a science that studies human behaviour as a relationship b/w ends and scares means which have alternative uses

concepts of supply in microeconomics
identify a demand and a supply curve
there's a difference
Aryan
Demand curve shows that how supply and others conditions affect on demand of a particular thing and what percent demand increase whith increase of supply of goods

Hi Sir please how do u calculate Cross elastic demand and income elastic demand?
