TSI Parabola Template, Transparent, 122 × 68 mm

TSI Parabola Template – Curve Template for Function Graphs

The TSI parabola template is a transparent curve template made of crystal-clear plastic, which you can use to draw function graphs neatly. It is one of the most important aids in secondary school maths. The unit parabola and the sine, cosine and tangent curves are punched out of the template. It has an inking edge.

At 122 × 68 mm, the template fits in any pencil case. Because it is see-through, you can see the coordinate system and your points underneath as you position it.

How to draw a function graph

First work out a table of values and plot the points on the coordinate system. Then position the template so that a section of the curve passes through as many points as possible, and trace along it with your pencil. Draw the curve in sections and let the pieces overlap slightly, so the line runs smoothly. When using ink, the inking edge rests on the paper so that the ink does not run under the template.
