A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve. An Order 2 polynomial trendline generally has only one hill or valley. Order 3 generally has one or two hills or valleys. Order 4 generally has up to three.
The vertical profile of a highway is made up of straight lines (grade lines) and curves, as shown in the following figure. The curves joining the grade lines are called vertical curves, and their function is to make a smooth transition from one grade to another.
