Evaluate the definite integral of the odd function
over the interval
The graph is shown in
[link] . We can see the symmetry about the origin by the positive area above the
x -axis over
and the negative area below the
x -axis over
We have
The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
The area under an even function over a symmetric interval can be calculated by doubling the area over the positive
x -axis. For an odd function, the integral over a symmetric interval equals zero, because half the area is negative.

A dodecahedron is a Platonic solid with a surface that consists of 12 pentagons, each of equal area. By how much does the surface area of a dodecahedron increase as the side length of each pentagon doubles from 1 unit to 2 units?
With
p as in the previous exercise, each of the 12 pentagons increases in area from 2
p to 4
p units so the net increase in the area of the dodecahedron is 36
p units.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
