よくある質問
What is the Bradis table?
The Bradis table is a reference table of pre-calculated trigonometric values (sin, cos, tan) for angles, originally compiled by V. M. Bradis.
What angles are included?
This table covers angles from 0° to 90° in 1° steps with values to 4 decimal places.
Why is tan 90° undefined?
At 90°, the cosine is zero, so tan = sin/cos involves division by zero, making it undefined.
How accurate are these values?
Values are computed using JavaScript's Math functions and rounded to 4 decimal places, providing high accuracy for practical use.
