Gross Domestic Product (GDP) is one of the primary indicators that the government, economists and other stake holders use to gauge the stability of a country’s economy. It measures the size of a country’s economy as it represents the monetary value of all goods and services produced over a time period. GDP estimates are commonly used to measure the economic performance of a country and also measure the relative contribution of the industrial sector. In formulating the model, we considered a four pair model, six pair model, and eight pair model. The result shows that at best Nigeria GDP contains four pair of the sine and cosine functions.
