Question

when would you use a problem like evaluating each determinant in real life?

Answer 1

Consumer tastes/preferences -- e.g. small cars versus big cars
Number of buyers in the market -- e.g. population growth
Buyers income -- e.g. changes in per capita incomes
Seasonal factors -- e.g. weather, holidays
Consumer expectations of future prices and income -- e.g real estate prices

Answer 2

Great! thanks so much!

Answer 3

thanks.

Answer 4

You will use a lot of determinants in multivariate calculus. Believe it or not, they make some theories easier to understand if you can use minor determinants!

Answer 5

Also in Geometry: Calculating volumes of parallelepiped (determinant of 3, 3dimensional vectors - | vector(1);vector(2);vector(3)|

Answer 6

hahaha if that isn't enough i could easily go get my linear book and look up the chapter on : Applications of determinants
