The Tool That Finally Makes Trig Click 

By Brady Richter, Founder of Trigonometer LLC 

Ask almost any math teacher about trigonometry, and you’ll hear some version of the same story. Students can memorize trig formulas: SOH-CAH-TOA. They can pass a quiz on it. But come November, when the unit circle appears in its full glory (six trig ratios, four quadrants, radian measures, and a whole lot of special angles), something goes wrong. The formulas blur together. The signs flip in mysterious ways. And the student who felt confident in September is suddenly lost. 

That gap between memorization and understanding is exactly what the Trigonometer was designed to close.
