Lens; tool for convex and concave lens or mirror Global description When placing the tool with its shortest straight side horizontally, the tool Is symmetrical. It could be describe as a traditional three story house. However, the top part is curved. The ground floor is a big rectangular window, the mirror template. The first floor has a window with the shape of a concave lens. The second floor shows a window representing the convex lens. …
Parabola; X to the power of 2 Detailed description The inner space of this U-shaped tool has the contour of the formula X to the power of two. The two poles of the U have indented centimetre indications along the outside. Three medium size alignment indents are provided near the bottom; one in the middle and one in each of the two poles. Pushpin markers are provided in the top surface of the tool. The …
SinTang; combination tool for the sine, cosine and tangent graph Global description The SinTang tool combines graphs for two formulas; the sin(X) and the tan(X). More precise, a half period of the sine graph and a quarter of the tangent graph. The sine graph, is the ‘hill’ contour which is the first half period of the sine graph. The cosine is a to the left shifted sine graph. When placing the tool looking at the …
Sine graph Photo: The first half of the sine graph has been drawn, the tool is rotated 180 degrees so the second half can be created. Draw an X axis with the ruler. Mark the X=0 and X=180 degrees position. The distance between the two marks is eight centimetres. Align the two two centimetre indications of the tool with the X axis. Draw the contour line for the sine from the X value of 0. …
Parabola manual Photo: A parabola has been drawn at X=0 and Y=0. The tool is positioned to create a second one at X-3 and Y=2. Draw an X and Y axis. Align the bottom indent with the Y axis and the ones in the poles with the X axis. Draw along the contour of the tool. You may choose any other coordinate as the minimum for the y value. The centimetre indications help to align …
Lens manual Photo: for the application the tool is rotated 90 degrees. The median light beam is drawn. A convex lens has been drawn. The tool is positioned to create the mirror. Draw a line with the ruler to represent the median light beam. Align the tool on the line. Draw the inner contour for the mirror, the convex or the concave lens. You can add additional light beams to show light breaking and reflection …
Hyperbole manual Photo: An X and Y axis are drawn. The graph is drawn in the first quadrant. The tool has been rotated 180 degrees clockwise so the second part can be created. A pushpin is at position X=0,Y=0. Draw an X and Y axis with the ruler Be aware, the effect of the additional material is also that the actual X and Y axis are covered by the tool. Align the tool with the …
GraphGrid frame manual Preparation The default setup has rubber bands every two centimetre in horizontal and vertical direction, so forming a grid. Two rubber bands go around the frame to indicate two axes. However, before mounting the GraphGrid frame on the TactiPad make sure all rubber bands are provided according your preference. Low and high rubber bands – Using differences in height The framework of the GraphGrid has a thickness of four millimeters. Therefore there …
The Spur Wheel Template Detailed description of the spur wheel template There are different types of spur wheels. This shape represents the mechanical properties with which the force can be maximised. When you interlink two wheels of this type, their teeth always have a point of contact under an angle of 90 degrees when rotating. Although it looks like an arbitrary number of teeth can be placed in a circle, this is not the case. …
The Regular Polygon Template Detailed description of the regular polygon template The set contains templates for regular polygons with five, six, seven, eight and nine corners referred to as pentagon, hexagon, heptagon, octagon and nonagon respectively. The radius of the polygons ranges from two to eight centimetres. In a regular polygon all corners have the same angle. The corners are interconnected with lines that have all the same length. Another way to describe a polygon: …
