Which formula would you use to determine taper when the Included Angle is given?

To determine taper using the included angle, the correct formula involves understanding the relationship between the angle and the taper per foot. The formula Taper Per Foot = 2 * inTan(Included Angle) utilizes the tangent function of the included angle in order to calculate the taper that occurs over a specified length.

The tangent function relates the angle to the ratio of opposite side (the taper) to the adjacent side (the unit length you are considering, typically a foot). Specifically, by multiplying the tangent of the included angle by 2, you effectively account for the taper on both sides of the angle, reflecting the total taper per foot of the workpiece.

This formula is rooted in trigonometric principles, where you use the tangent of half the included angle to find the corresponding taper per foot. Thus, this formula correctly calculates the required taper based on the given included angle.
