Linear\u2014Indicates that the VF is a linear function of the VRMA.

Cos\u2014Identifies the VF as the cosine-based function of the VRMA. Sec\u2014Identifies the VF as the secant-based function of the VRMA.

This factor positions the y-intercept of the specified function. By definition, the zero factor is not applicable to any of the trigonometric vertical functions (COS, SEC, COS-SEC, or SEC-COS). The y-intercept is defined by these functions. Low Cut angle\u2014Defines the VRMA angle below which the VF will be set to infinity. High Cut angle\u2014Defines the VRMA angle above which the VF will be set to infinity. Slope\u2014Establishes the slope of the straight line used with the Linear and Inverse Linear vertical-factor keywords.

The growing accumulative cost to reach a cell is multiplied by the resistance rate and added to the cost to move into the subsequent cell.It is a modified version of a compound interest rate formula that is used to calculate the apparent cost of moving through a cell. As the value of the resistance rate increases, it increases the cost of the cells that are visited later. The greater the resistance rate, the more additional cost is added to reach the next cell, which is compounded for each subsequent movement. Since the resistance rate is similar to a compound rate and generally the accumulative cost values are very large, small resistance rates are suggested, such as 0.02, 0.005, or even smaller, depending on the accumulative cost values.The values must be zero or greater.
