How to enter exact values, units and rounding
Enter the numerical value in the units shown beside each field. Use pi, sqrt(3), acos(3/5) or asin(4/5) for exact values. Trigonometry uses radians. Give a final decimal in fields asking for 3 significant figures. For sets of angles use pi/3, pi/2; for radius–angle pairs use (4,5); (10,4/5). For intervals use (16/(pi+1),16). Do not round an intermediate angle before finding a segment area.
