Answer:
The most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. cos(2x) = cos² (x) - (1 - cos²(x)) = 2cos²(x) - 1. = 2cos²(x) - 1.

It should be noted that GDP deflator simply measures the changes in price for goods and services.
<h3>What is GDP?</h3>
Your information is incomplete as the figures aren't given. Therefore, an overview will be given.
Gross domestic product simply means the total monetary value of the finished goods and services that are produced in a country.
The formula for calculating the GDP deflator will be:
= Nominal GDP/Real GDP × 100
Also, the formula fro calculating real GDP per capita will be:
= Real GDP/Total population
In conclusion, the real GDP is the GDP of a country that has been adjusted for inflation.
