First we have proportional parts of all numbers up to 100; then on one page three-place logarithms of numbers and of the six trigonometric functions, natural and logarithmic.

Trigonometry Table is a table that helps us to calculate the values of trigonometric ratios for common angles such as 0°, 30°, 45°, 60°, and 90°. But it is difficult to memorise the values.

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core ...

At an American Mathematical Society meeting, high school students presented a proof of the Pythagorean theorem that used trigonometry—an approach that some once considered impossible ...

Soon after, Al-Khwārizmī (780 to 850) produced accurate sine and cosine tables in “Zīj al-Sindhind” (820). It is through this work that that knowledge of trigonometry first came to Europe.
