Introducing an Innovative Tool for Teaching and Learning Trigonometry |
The TrigRuler
See How Trig Works!
The TrigRuler is an innovative, patented learning tool that displays the trigonometric sine and cosine along with the angle.
Existing geometric figures can be measured to find the angle, sine and cosine simultaneously in one single operation. Likewise, using a pencil and the TrigRuler, a desired geometric figure with known dimensions can be constructed in a similar operation.
The TrigRuler enables students to see how Trig works as they manipulate the device in their hands while working through exercises and problems. This visual and tactile approach leads to a better understanding and longer retention of the basic foundations of trigonometry.
The TrigRuler helps students develop an intuitive sense and a real feeling for how Trig works that will stay with them forever as they continue their study of mathematics.
The TrigRuler is made in the USA from highly durable, yet flexible clear plastic material measuring 11 ¼ inches allowing it to easily fit into a school book back pack.
