The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2Ï. So, a coefficient of b=1 is equivalent to a period of 2Ï. To get the period of the sine curve for any coefficient b, just divide 2Ï by the coefficient b to get the new period of the curve.
What is 'Economic Efficiency'. Economic efficiency implies an economic state in which every resource is optimally allocated to serve each individual or entity in the best way while minimizing waste and inefficiency. When an economy is economically efficient, any changes made to assist one entity would harm another.
Economic development can be defined as a sustained community effort to improve both the local economy and the quality of life by building the area's capacity to adapt to economic change (Loveridge and Morse). This definition suggests a distinction between economic growth and economic development.conomic development can be defined as a sustained community effort to improve both the local economy and the quality of life by building the area's capacity to adapt to economic change (Loveridge and Morse).
