Table of Trigonometric RatiosBảng tỉ số lượng giác

Values for 1° to 89°, rounded to four decimal places, so most of them are approximations: write ≈, for example tan 39° ≈ 0.8098. A link such as trig-table.html#d39 jumps to one row.Giá trị từ 1° đến 89°, làm tròn đến bốn chữ số thập phân, nên phần lớn là giá trị gần đúng: viết dấu ≈, ví dụ tan 39° ≈ 0.8098. Đường dẫn dạng trig-table.html#d39 mở thẳng tới một dòng.
