• Titled " Problema wie aus bekannt gegebenem sinu eines Grades, Minuten oder Sekunden alle folgenden sinus aufs leichtests zu finden und der canon sinuum zu absolvieren sei " he described various measures to calculate sines.
• Johannes Kepler called the Canon Sinuum the most precise known table of sines . ( reference ? ? ? ) B黵gi explained his algorithms in his work Fundamentum Astronomiae which he presented to Emperor Rudolf II . in 1592.
• B黵gi constructed a table of sines ( " Canon Sinuum " ), which was supposedly very accurate, but since the table itself is lost, it is difficult to be sure of its real accuracy ( for instance, Valentinus Otho's " Opus Palatinum " had parts which were not as accurate as it was claimed ).
