This is an app for calculating trigonometric functions (trigonometric ratios) in mathematics such as sine (sin), cosine (cos), and tangent (tan).
Most smartphones can display more digits than many books and websites list.
Enter the angle you want to know and click "=" to display three values.
Values are displayed as decimals rather than roots or fractions.
The input angle also supports negative numbers and decimal numbers.
