Global description
The hyperbole represents the function 1 divided by X (1/x). The tool is L-shaped. Both parts of the L have a length of 10 centimetres. The inner corner of the tool is curved. By nature of the formula, the tails of the tool become very thin. To maintain the sturdiness of the tool, additional material has been added.
For alignment purposes, a small square is left out at the lower left corner of the tool (X=0 and Y=0). In addition, near the ends of the curve, a flat section is provided.
The graph contour endings are equipped with pen blockers. Pushpin markers are provided at the top surface.

Detailed description
The formula represented in this tool is a smooth curve only going down, seen from X equals 0 to X equals 8. Along the curve, small indents are provided to indicate Y-values corresponding to X-values equal to 0,25, 0,50, 1, 2, 3, 4, 5, 6, 7 and 8 respectively.
Hyperbole Tool manual
Draw an X and Y axis with the ruler
For convenience, place a pushpin in the crossing of the X- and Y-axis. When positioning the tool, be aware that the additional material covers the X- and Y-axis. Therefore, align the tool with the two axes by placing the flat sections at the tails against the axis. Draw along the contour of the tool.
Rotate the tool 180 degrees clockwise. Align the tool with the axes and draw the second part of the graph.
