20140215840 | Trigonometer - The New Trigonometer is a genuine device used to compute the sine, cosine, and tangent of angles. Consequently, the device could also be used to calculate the reciprocal sine, cosine, and tangent functions. Modern calculators can easily compute the above mathematical functions, thus the importance of this device is not in its ability to do such calculation. On contrast, the New Trigonometer has many aspects of novelty, which need to be protected. Indeed, it adds to the conventional protractor three new components: the Tangent Calculator, the Sin/Cos Calculator and the Angle Tracking Device. Moreover, these components are assembled in a genuine way, which makes the new trigonometer a tangible reflection of the trigonometric circle. Thus, the New Trigonometer becomes a significant educative tool for the students due to its illustrative characteristics, and a useful measurement tool in carpentry due to its holistic features and ease of use. | 08-07-2014 |
