Calculate trigonometry calculator using the values and assumptions you provide.

Results depend on the assumptions entered; verify professional or safety-critical decisions independently.

These short examples use the same inputs and core calculation as this tool. Adapt validation and formatting to your application.

JavaScript

const degrees = 30, radians = degrees * Math.PI / 180;
console.log(Math.sin(radians)); // 0.5

TypeScript

const degrees = 30, radians = degrees * Math.PI / 180;
const sine: number = Math.sin(radians);
console.log(sine); // 0.5

Python

import math
print(math.sin(math.radians(30)))  # 0.5

Java

System.out.println(Math.sin(Math.toRadians(30))); // 0.5

Console.WriteLine(Math.Sin(30 * Math.PI / 180)); // 0.5
