The New Trigonometer is a device that tangibly reflects the function of the trigonometric circle: it is like you have a trigonometric circle between your hands. The device is invented by the Lebanese Mechanical Engineer Patrick Kattan. It was registered in Lebanon on 04/02/2013, under the patent number 9921, and published in the Lebanese Gazette on 18/04/2013.

The name trigonometer derives from trigonometry. Though it does not exist in the dictionary, the name trigonometer generally refer to a device used in trigonometry. To avoid any ambiguity, the world new is added, so users can clearly identify the device from previous devices having the same name, in case they exist.

The new trigonometer adds to the conventional protractor three items: - The tangent calculator (used to find the tangent of an angle.) - The Sin/Cos Calculator (used to find the sine and cosine of an angle) - The angle tracking device, to enable the users with easy tracking of angle, and to help them in executing the desired calculations.

The importance behind the trigonometer is not its capability to calculate the above trigonometric functions, but its ability to tangibly reflect how a trigonometric circle works. As a consequence, the trigonometer is a useful educative too, and has the following characteristics: -Illustrative: it enables its user to visualize how a trigonometric circle functions; such illustration enhances the ability of the students to understand the trigonometric functions, since the students can tangibly interact with these functions when using the device. -Accurate: it enables its user to read the exact values of the trigonometric functions listed previously, since the values of these functions are irrational numbers, which can only be expressed accurately using a geometric representation (similar to that provided by the device.) Note that a modern digital calculator gives approximate values of these functions, rounded to a number depending on the calculator's accuracy. -Practical: it enables its user to safe time; instead of drawing one trigonometric circle to each angle, the user can switch between angles and numbers by simply rotating and tilting the Angle Tracking device and the Sin/Cos Calculator.

The trigonometer could also be used in carpentry; indeed, it will help carpenters in doing cuts, calculating dimensions of studs and articulated meshes, and in calculating slopes. Due to its illustrative characteristics, it enables its users to direct observe the geometrical similarities between per unit dimensions and actual dimensions of wood structures, intercepting the same angle.
