The taper ratio of a wing is the ratio between the tipchord and the rootchord: ct/cr

A Taper Lock Bushing is a mechanical joint used to connect a shaft to another part. They are made of steel and feature a tapered surface to lock onto the shaft. They also feature a thread and key-way for additional security. Taper lock bushings are available in different sizes and can be interchanged with a variety of other bushings from other manufacturers.

The purpose of measuring taper angle is to obtain taper angle

This is the formula for calculating a taper:

Large diameter of the taper minus the small Diameter of the taper divided by the length of of the taper will give you the taper per inch.

You will also need to know the included angle of the taper if you ar cutting this taper.

This formula would be Tangent of the included angle divide by 2.

This means that it is the opposite of the normal direction that a taper goes. Example; If a normal taper goes to the left, a reverse taper goes to the right.
